Abstract Scope |
Numerical simulations have played an important role in accelerating alloy design in recent years. Especially, CALPHAD-based simulation tools have significantly reduced the time scale for new alloy development from several decades to a few years. Computherm LLC developed Pandat software to empower material scientists with CALPHAD tools for ICME applications. Recently, we developed PyOptimizer, a calibration tool to optimize kinetic parameters based on a given set of experimental data. These optimized parameters were then used to simulate thermo-mechanical processing of aluminum alloys which will be discussed in the presentation. Furthermore, we recently developed SDKs that provides an efficient coupling of CALPHAD data with FEM simulations of metal processing. This approach enables us to utilize mean-field models in Pandat to simulate spatially varying microstructure properties in process simulations such as rolling and forging. Few examples of these processing simulations will also be discussed. |
