Abstract Scope |
Many of the structural materials designed for harsh environments are multicomponent alloys, and thus the investigation of the composition-dependent properties is desired to optimize the alloys’ functionality. This process, however, can be tedious as the number of possible combinations of the compositions of multicomponent alloys is enormous. Combinatorial synthesis and high-throughput experiments offer an effective route to acquire a large number of experimental property data. To characterize composition-dependent phase stabilities and physical properties of solid solution strengthened Ni-based alloys, we combinatorially synthesized Ni-Fe-Cr ternary systems and carried out high-throughput measurements. We used magnetron co-sputtering to fabricate the thin film materials library and performed x-ray diffraction, nanoindentation, and 4-probe resistance mapping experiments. We discuss the experimental results and the composition optimization process for the Ni-based alloys with high strength. |
