3 FROM THE EDITORS 3 From the editors The annual report from the Department of Materials Science and Engineering (DMSE) consists of two parts. The first part comprises Science Stories, Publication List and List of Equipment and is primarily intended for external readers. The second part is intended for the archives. DMSE is an average sized department at NTNU with respect to the number of academic and technical staff. However, taking into consideration PhD students and post docs engaged in the research project portfolio, DMSE is a rather large department. DMSE has 19 professors, 4 associate professors, 12 adjunct professors, 14 professor emeritus, a technical and administrative staff of 21, and finally 76 PhD students, post doctoral fellows and researchers. The management of the Department changed in August when professor Lars Arnberg and professor Tor Grande resigned as Department Head and Deputy Department Head respectively. Tor Grande was elected the new Department Head and professor Knut Marthinsen the new Deputy Head. One of the laboratories of the Department, Chemistry Building II was completely renovated during the year and the whole group of Inorganic Chemistry was temporarily relocated in Chemistry Building I. The renovation was completed in December and the group could move back into very modern, well equipped laboratories. Also the group of Electrochemistry moved into the new laboratory and the department is now basically located in just two buildings. The Department receives students from two sources: The Materials Technology students are enrolled from their first year. Students from the program of Chemistry and Biotechnology which specialise in Materials chemistry and energy technology are enrolled from their third year. In addition the department recruits students from the Norwegian Colleges and the international master program in Light metal production. The trend of increasingly better enrolment to Materials Technology continued also in students applied with Materials Technology as their first choice and 30 were admitted to the program. The department is also responsible for all teaching in general chemistry for engineering students, about 800 in total. The number of candidates graduating from the Department has increased in recent years. The PhD degree has been granted to 14 candidates this year compared to 11 in students have completed their Master of Science degree compared to 19 in PhD students and 29 Master students are in progress. The 24th International Course on Process Metallurgy of Aluminium, arranged from May 18 to 27, had an attendance of 73 participants from 27 countries. The course of Fundamentals and their application in aluminium production had an attendance of 36 participants from 12 countries. A one week course, Solar Cells Power of the Future was arranged by the Department in cooperation with the Board of European Students of Technology. The course attracted 26 students from 15 European countries. A number of senior professors at the department have retired over the last few years, the last in the row was professor Harald Øye in A new generation of faculty members is being recruited. In 2005, Svein Sunde was hired as a Professor of Electrochemistry, Kjell Ove Kongshaug was hired as an Associate Professor of Nanotechnology, Jarle Hjelen as a Professor of Physical metallurgy and Lifeng Zhang as a Professor in Process metallurgy. Professor emeritus Nils Ryum was awarded Sam Eyde-Fondet/ Polyteknisk Forening's Jubileumspris 2005 and Professor emeritus Harald A. Øye received the Polyteknisk Forenings Hederspris. The number of publications in peer reviewed journals in 2005 is 70. The annual budget of the Department is now actually dependent on the number of publications in addition to the number of PhD and Master Candidates, and DMSE are one of the Departments at NTNU with the highest average number of publication per faculty annually. The Department has a close cooperation with SINTEF, resulting in a new Gemini Center, Solar cell Materials, in The Department also has a close contact with Norwegian and international Industry.

6 6 SCIENCE STORIES Historical metallurgy in Trøndelag The early process for ironmaking, based upon a shaft furnace with slag pit has been documented at some 300 sites in the province of Trøndelag. Ongoing metallurgical research at the department is directed towards development of new and better materials, the economic use of energy, reclaiming of waste material etc. However, as long as a university also covers subjects such as history, archaeology, geology and ethnology the department has a role to play. The early process for ironmaking, based upon a shaft furnace with slag pit has been documented at some 300 sites in the province of Trøndelag tons of slag have been found at each site, representing about the same amount of metal. The production reached a peak around year 200. For some reason this technology was abandoned around year 600 AD while a new process with smaller, side-tapped furnaces was introduced around 800 AD. However, this type, so common in the Østland area north and west of Oslo, has hardly been registered north of Gauldalen. Nobody has been able to reproduce these two early processes. As a paradox they were in full use in primitive societies of the past. These problems have been the subject of a project between the department and Gauldal Secondary School where the students have made charcoal in a large kiln and fetched bog iron ore as well as characteristic clay at selected places. The raw materials have been studied by chemical analysis, XRD and other methods in the university. The clay has been tested as a raw material for pottery, as an introduction to the manufacturing of a ceramic shaft. Ironmaking will follow. Arne Espelund Fig. 1.

7 SCIENCE STORIES 7 In-situ deformation of aluminium in the SEM A new meso- to micro scale approach to explore texture evolution. Modern production of cars demands a high degree of automation involving tight tolerances of the various components. This is challenging the extrusion industry, since extruded profiles often have strong microstructure- and texture gradients through the thickness, and these gradients affect the mechanical anisotropy. In order to understand how gradients affect the mechanical anisotropy, one can investigate how the microstructure and texture in the different sections through the thickness evolve during deformation. Such studies can now be performed by applying a specially developed in-situ deformation technique. Here the microstructure of the specimens, deformed by simple tension inside the chamber of a SEM, is mapped by an Electron Back-Scatter Diffraction (EBSD)- technique. The electron beam scans an area of interest and the crystal orientations are automatically calculated on the basis of an electron diffraction pattern from each pixel. This technique provides information about basic deformation mechanisms including deformation gradients, identification of active slip systems and lattice rotations on the grain and sub-grain level. The knowledge from such investigations helps understanding anisotropic plastic flow which in turn premises the formed shape (and tolerances) of extruded profiles. Some examples from the work of PhD student Hans Bjerkaas as shown in the figures. The material studied is an extruded AA6063 profile. The left EBSD-map shows the microstructure before deformation: - Most of the grains have a red colour indicating a <100> direction parallel to the extrusion direction (the crystallographic direction parallel to extrusion direction is given by the colour coding in the triangle). The pole figure underneath the left micrograph shows presence of a strong cube texture, i.e. the three <100> directions are parallel to the extrusion-, transversal- and normal direction respectively. The micrograph shows an EBSD map of the same area after 17% deformation. The grain shapes and the colours within the grains have changed, indicating lattice rotations during plastic deformation. The pole figure underneath the micrograph shows the corresponding development of the crystallographic and the new texture components. The studies have shown that in-situ deformation can be a powerful tool when characterizing local texture development upon plastic deformation behaviour of industrial alloys.

8 8 SCIENCE STORIES Nanostructured silica materials Silica aerogel is one of the world s lightest materials marked the end of the EU-project HILIT+. The main goal of this project has been to demonstrate an efficient environmental-friendly process for the preparation of 60x60 cm aerogel insulated windows. The project consortium consisted of 9 partners from France, Germany, Denmark and Sweden in addition to NTNU and was a follow-up from previous EU-projects. Silica aerogel which is among the worlds lightest material, is consisting of a network of nanosized silica particles as shown in Fig. 1. The porosity can be up to 98 %. The pore size is in the mesorange giving a material which is transparent and with a very low thermal conductivity. Surface area can be as high as 1000 m 2 /g. The aerogels were fabricated by a sol-gel route using polyethoxydisiloxane precursors followed by supercritical drying from CO2 to avoid fracture and shrinkage during drying. Due to the high porosity, both the wet gels and hence aerogels have a low mechanical strength and our main contribution to the project has been to increase the strength of the wet gels. The strategy to increase the strength has been to age the wet gels in different liquids where partial solubility of silica is promoted. During the aging, dissolved silica is transported to the necks in between the particles. Mechanical characterization of wet gels has been performed by 3-point beam bending shown in Figure 2 where modulus of rupture, sheer modulus and permeability of the wet gels have been measured. Through the HILIT+ project several 60x60 cm 2 demonstration windows have been made. Figure 3 shows a smaller demonstration window. Mari-Ann Einarsrud Fig. 1. Structure model of silica aerogel.

9 SCIENCE STORIES 9 Porosity development in anodes for primary aluminium production A new application of Image Analysis Porosity Measurements. The development of porosity in green composite carbon materials is important for their chemical and physical properties in the baked state. In the Hall-Héroult process an unfavourable pore size distribution and structure is detrimental to the anode consumption. Pore development depends on the raw materials and on the paste production process. Pitch and coke particles must be distributed evenly and smaller particles fitted into the voids between larger particles in order to obtain a homogeneous paste. If not, intraparticle porosity will increase, and the paste will contain a higher amount of trapped air and volatiles at the forming stage thus leading to excessive porosity development during baking. Anode consumption has mainly been addressed by studies of catalytic activity and little or no attention has been paid to structure and porosity, due to the complexity of the green state and a lack of good analytical methods. Our image analysis technique is a valuable tool for studies of both the green and the baked state of carbon materials and is in this work used for porosity determination. A continuous pore size distribution from 1 µm to 10 mm is registered and the method thus covers a larger range than mercury porosimetry. Pilot-scale anode samples were produced from a single source petrol coke in a five-factorial experimental design with the variable factors pitch content, aggregate size distribution, mixing time, mixing techniques (sigma blade and intensive mixers), and heating rate during baking. The mixing technique and the pitch content have the strongest impact on both the porosity and the specific electrical resistivity of the anodes. Intensive mixing results in higher apparent density as can be seen in Fig. 1. Fig. 2 shows averaged pore size distribution curves. Conventional mixing of 14 % pitch anodes shows large pores due to aggregate crushing and void formation during the mixing and the forming stage. In the case of intensive mixing, less of the small pores (8-40 µm) are present. This is due to better filling and impregnation of coke particle pores and interparticle voids with pitch. With increasing pitch content more pitch is available in the intergranular space to penetrate the coke pores and to form thicker binder coke films around the coke particles. In this case the pore size distribution curves tend to peak around 100 µm which is typical for pitch coke where pores form by escaping volatiles. Conventional mixing results in less homogeneous and more porous anodes compared to intensive mixing (Fig. 3). The intensive mixer provides higher dynamic pressure gradients that result in improved filling and impregnation of pores and voids. In the conventional mixer the coke particles are crushed during mixing. This causes binder deficiency and thus higher porosity.

10 10 SCIENCE STORIES ULCOS ultra low CO2 production of iron and steel The production of iron and steel causes large emissions of CO2. Electrolysis by using an inert oxygen evolving anode represents an attractive alternative. The department is a partner of ULCOS, one of the largest projects supported by the EU. The primary goal of the project is to develop a new process to produce iron and steel with strong reduction of the emissions of CO2. The iron and steel industries are major contributors to the emissions of CO2, which is regarded as the most important greenhouse gas. About 1000 million tonnes of iron is produced annually in blast furnaces and electric arc furnaces. The emissions from a blast furnace amount to about 2 kg CO2/kg Fe. Several routes to reduce or eliminate CO2 emissions are being studied in the ULCOS project. The Department of Materials Science and Engineering participate in two different subprojects of ULCOS. One group is involved with studies of iron production by using natural gas. The other is investigating electrolysis, which is one of the more dramatic alternatives to produce iron. Electrolysis using an inert oxygen evolving anode will completely eliminate CO2 emissions for the production process if the electric energy can be produced from renewable sources of energy. Electrolysis can be carried out in aqueous electrolytes, molten salts or molten oxides. The work in Trondheim has been focused on the use of molten salt electrolytes. The major challenges have been to find an electrolyte which dissolves enough hematite to allow for a high current density for electrodeposition of iron and to obtain smooth electrodeposits of iron. Several electrolytes were tested, including molten chloride mixtures based on CaCl2, pure fluoride and mixed chloride/fluoride electrolytes. The performance of candidate inert anode materials to evolve oxygen was tested during electrolysis. Electrodeposits of pure iron were obtained in many electrolytes. The most promising results were obtained in the molten system KF-NaF-CaCl2. The solubility of Fe2O3 was determined to be of the order of mol% in melts containing ~10 mol% CaCl2. In these electrolytes pure iron was deposited at current densities exceeding 0.5 A/cm 2 using a rotating Fe cathode to increase the rate of mass transfer of Fe(III) species. The current efficiency with respect to iron was consistently found to be above 95%.

11 SCIENCE STORIES 11 Fluidity of Al foundry alloys An improved fluidity test method for studying the parameters affecting fluidity in Al foundry alloys. Foundry and automotive industries are concerned with the fluidity of their alloys because this affects the soundness and quality of their cast products. Poor or insufficient fluidity results in an increased rejection rate of cast products and limits their cross section. The higher the fluidity of an alloy, the thinner is the mould-wall that can be achieved. The term fluidity in the foundry is used to indicate the distance a molten metal can flow in a mould of a constant cross-sectional area before it solidifies. Fluidity in foundry is a complex technological property and it depends upon many factors, e.g., chemical composition, solidification range, heat of fusion, casting temperature (superheat), mould coating, oxide/particle content. The first fluidity test appeared in 1902 and, since then, several equipments for fluidity testing have been developed and modified. However, there is still a need for a reliable fluidity test. An improved fluidity test method has been developed and tested in cooperation with SINTEF Materials and Chemistry. The geometry of the fluidity spiral method is shown in Fig.1. Due to an automatic control of the casting temperature and pouring height, the system provides constant superheat and pressure head which allow for highly reproducible fluidity measurements. This fluidity method has been used to study many factors affecting fluidity such as casting temperature, oxide content, mould coating, grain refinement etc. Fig. 2 shows the team from the department and SINTEF that has carried out the work and is a part of the program NorLight, which involves many Norwegian industries and international cooperation. Fig.s 3 and 4 show some of the most important results of this work. The increase of the casting temperature (hence melt superheat) increases the fluidity of an Al-7wt%Si alloy (Fig. 3). The addition of 20% turning chips (recycled material from FUNDO WHEELS AS) to a standard A356 alloy increases both inclusions and oxides content, and decreases fluidity.

12 12 SCIENCE STORIES Components for the transport industry High pressure die casting an example of a good collaboration between industry and university research. High Pressure Die Casting (HPDC) is a well established casting method, particularly suited for fully automatic, high productivity, high volume production of complex near net shaped parts with weights ranging from a few grams to more than 15 kilograms. The transport industry shows a great interest in this technology because the technique offers light metals solutions with the integration of many functions into one part. The new trend is to use modern modeling technology to develop the process further to obtain better properties of the products and with less variation in properties than before. The market grows annually at about 10 %. Norsk Hydro has installed a modern, well equipped 420-ton cold chamber HPDC machine at the plant in Porsgrunn. Melting and melt treatment facilities are set up nearby to make pilot scale casting easy and performed at an optimum way. The institute has the option to use these facilities for practical education of students in casting and for research. This enables the institute to do pilot scale casting experiments of a high numbers of castings effectively, with good documentation of process parameters and with melts pretreated at specifications. Joint use of this equipment and collaboration on projects is to mutual benefit for the quality of work and research. Projects on high pressure die casting at the department include investigations on how process parameters influence structure and properties of cast components, and investigations of heat transfer between the die and the cast metal. Otto Lohne and Lars Arnberg Model of high pressure die castings with testing materials (red), pipelines for cooling (blue) and a device for measuring the temperature (green).

13 SCIENCE STORIES 13 Microstructure control of steels through dispersoid metallurgy Non-metallic particles are concidered detrimental to steel but not if they are small and numerous. Development of the first generation of grain refiners for steels is based on the experience that oxides and sulphides of rare earth metals can effectively be transferred to liquid steel via ferroalloys containing small inclusions dispersoids and these dispersoids will then provide a finer grain size in the cast steel. These particles are often remarkably persistent and can survive in the steel melt for an appreciable period of time without loss of identity. A master alloy containing a high number density of dispersoids in the 1μm size range, is added to a clean steel melt being low in oxygen and sulphur. The master alloys can be produced in two different ways: 1) The melting & quenching route means that the alloy components first are mixed and melted in an induction furnace and then rapidly quenched to achieve the desired distribution of the dispersoids in the grain refiner 2) The value-added DRI (Direct Reduced Iron) method involves mixing of iron oxide powder with other metals or oxides. The pellets made from these blends are subsequently reduced in a controlled atmosphere at high temperatures to remove excess oxygen from the master alloy, leaving behind a fine dispersion of stable oxides in the iron matrix. Figure 1 shows scanning electron microscope (SEM) images of two sulphur-based master alloys produced via the melting & quenching route. The question whether the MnS dispersoids could be converted to CeS or some other reaction product following dissolution of the sulphur-based master alloy into a clean steel melt containing cerium in solution has been done using the master alloy shown in Fig. 1 (a). The steel was cast immediately after the addition was made. In some cases it was also possible to observe the conversion of MnS to CeS as can be seen in Fig. 2 (a) Øystein Grong and Leiv Kolbeinsen 5 µm a) 1 µm a) 5 µm b) 0,5 µm b) Fig. 1.
