Abstract Scope |
Multi-component alloys used in commercial applications are engineered to satisfy several design criteria such as strength, microstructural stability and corrosion resistance. However, finding new alloy chemistries and processing conditions to enhance material properties is a challenging task. In this talk, we will demonstrate how first-principles statistical mechanics techniques can provide critical insights into the design and discovery of multi-component alloys. Machine-learnt atomistic models informed by high-throughput electronic structure calculations will serve as inputs to statistical mechanics techniques to rigorously derive finite-temperature thermodynamic, kinetic and chemo-mechanical parameters. Insights from our calculations will be used to design multi-component refractory, magnesium and titanium alloys. Design rules discerned from simulations will be used to search for single-phase and precipitation hardenable chemistries across several material classes. The techniques and results presented in this talk provide important insights for the design of multi-component alloys. |
