| Abstract Scope |
Refractory Complex Concentrated Alloys (RCCAs), typically consisting of four or more elements in high concentration, are a class of materials that often possess remarkable structure-properties relationships. However, it is challenging to efficiently explore the multidimensional phase and composition space of these materials with conventional manufacturing routes. This talk presents recent efforts in implementing a high throughput alloy processing methodology to rapidly assess RCCA structure-properties relationships via metal Additive Manufacturing (AM). The methodology is outlined and select case studies are presented to illustrate the efficacy of the approach. High throughput Molecular Dynamics simulations that provide rapid insight into material properties predictions are also presented. Preliminary results demonstrate the value proposition of utilizing high throughput experimental processing and computational tools to accelerate materials development for AM.
