Agenda Introduction to Metatech Motivation and objectives Agile Materials Development Productivity Tools for Materials Development StahlDat SX the leading European database for steels JMatPro practical software for calculation of materials properties Selected examples Conclusion and summary 2
Introduction to Metatech Metatech is an independent Engineering company founded 2008 Focus: Materials Technology Innovation Services: Consultancy Research & Engineering Materials Software Customers: Industrial clients (Steel industry, Foundries Tube Mills, Metalworking Industry, Heat-Treatment, Automotive) 3
Motivation and Objectives Get there faster: Faster time to market Reduced costs Higher profit Select and develop high strength steel grades Cost effective Better performance Eco properties (lightweight design) 4
Example: Ultra high strength steel saves ~ 20 kg weight CPDUR TM 2000 Super lightweight drive-shaft: - Tubular design - Tensile Strength > 2000 Mpa - Elongation > 10 % Small scale industrial production has been started 5
Agile Materials Development New Materials Solutions in a Short Time How to get there? Laboratory Simulation Knowledge & Inspiration Use best practices from other industries to speed up materials development cycles, e.g. SCRUM Use design collaboration in materials development, e.g. by interdisciplinary teams 6
Design Collaboration in Materials Development Solution design workshops bring people and tools together TEAM (4-8 People) Research & Development Marketing & Sales Manufacturing & Quality PRODUCTIVITY TOOLS - JMatPro V7: Breakthrough materials simulation - StahlDat SX Pro: The best knowledge base for Steels Requirements Solution design Lab Verification 7
Agile Materials Development How much time takes a development cycle? 2 Weeks 10 Weeks Preparation & Workshops Vacuum melting Hot and cold rolling Testing Key enablers: Solution design workshops Use materials simulation and databases in workshops Reduce number of melts and cycles by knowledge and simulation 8
Productivity Tools for Materials Engineers Materials Simulation Materials Databases Fast and robust calculations Influence of chemistry and process on microstucture and properties All European steel grades Data from standards and research projects

JMatPro The Materials Property simulation CalPhad: Calculation of phase diagrams for multi-component systems JMatPro User-friendly application of CalPhad Calculation of materials properties 13
JMatPro at a glance Prediction of amount and composition of each phase Thermodynamics Physical models Calculation of properties for each phase as a function of temperature and composition Materials: Al-alloys Co-alloys Mg-alloys Fe-based alloys Ni-based superalloys Ti-based alloys Zr-based alloys Solder alloys Calculation of materials properties as a function of amount of phases and morphology using a mixture model Data export to FEA packages FEA Exporter: Ansys Forge Deform Deform HT Simufact Magma, etc
Information from JMatPro 1. Stable and metastable phase equilibria - Step temperature calculation - Step concentration calculation 2. Physical and thermophysical properties - Enthalpy, Cp, Latent heat - Volume change, density, and solidification shrinkage - Thermal expansion coefficients - Thermal conductivity and diffusivity - Electrical conductivity and resistivity - Liquid viscosity and surface tension - Young s, bulk and shear modulii 3. Microstructure evolution during processing - Solidification, Precipitation, Phase transformations, Reaustenitisation 4. Mechanical properties - Strength & hardness, - Creep, - Stress-strain curves
Phase equilibria of multicomponent alloys Get a feeling for effects of compositional changes
Example Boron-Steel: Optimize Titanium-Nitrogen Balance Objective: Maximize free Boron in Austenite
