| Abstract Scope |
To develop new refractory alloys and composites that can be used as blade materials for turbine engines operated at 1300C, refractory complex concentrated alloys (RCCAs) were designed and experimentally fabricated and tested. A large number of new compositions of the single-phase RCCAs were designed based on the high throughput computational design. Experimental verification of these RCCAs was conducted by both arc melting and laser powder bed fusion. Mechanical properties, including yield strength, ductility, hardness, and creep properties, were measured at both room temperature and high temperatures. Optimized RCCA compositions with a combination of excellent mechanical properties were selected based on the experimental and simulation results. The mechanical properties of RCCAs were enhanced by the second phase of carbides. |
