| Abstract Scope |
Designing multi-principal element alloy (MPEA) binders for hard metal composites with the objective of substituting elements such as cobolt has proven to be a formidable challenge. Various attempts have been made to approach the performance of, e.g., the tungsten-carbide cobolt system still with rather modest success. To address the design challenge of identifying novel MPEAs we approach it as a multiscale problem, making use of a range of methods from density functional theory based calculations to machine learning potential molecular dynamics to phase field modeling and micromechanics of metastable MPEAs. We define and address via calculations and experimental activities several metrics for design targets addressing both the behavior of the MPEA binder and its interaction with the reinforcing phase, such as tungsten or titanium carbide. The results provide insights to new alloy chemistries and to a set of metrics that can be used to systematically to design respective MPEAs. |
