Martensite in Computational Materials Design: An Interplanetary Opportunity: Charles Kuehmann1; 1SpaceX/Tesla
In the context of computational materials design, martensitic reactions provide fertile ground for creative metallurgy. With stress and strain dependent nonlinear mechanical response, temperature dependent activation, and diffusionless kinetics, martensitic transformations provide a large number of unique variables to the materials designer which they can use to create new useful properties and capabilities. These include ultrahigh-strength, shape-memory and superplastic effects, and enhanced toughness or plasticity. Materials that exploit these capabilities are employed just about everywhere. In order to harness the computational design of such systems, a quantitive predictive model of martensitic reactions, capable of extrapolation, is necessary and thankfully available. Such a model has been used to design toughened ultra-high strength steels, shape memory alloys and highly formable sheet steels. As requirements for new functionalities in materials increase to address society’s challenges, martensitic materials designs will become even more relevant and important.

On the Development of Theoretical and Experimental Tools for Design of Martensitic Steels: Annika Borgenstam1; 1KTH, Royal Institute of Technology
Materials development using ICME (Integrated Computational Materials Engineering) is a new approach that accelerates the design of new materials. For an ICME approach for the design of martensitic steels, ultra-high strength steels with improved ductility or stainless steels, theoretical as well as experimental tools are needed and development of these are the aim of the research center Hero-m. In this presentation, modelling achievements of the martensitic transformation as well as an improved understanding of the microstructural evolution will be highlighted.
