| Abstract Scope |
In this study, using a combinatorial thin film approach, we searched for alloy compositions in the MnFeCoNiCu system that exhibit superior mechanical properties and phase stability. Thin films with 2D composition gradient were fabricated using magnetron sputtering, and mechanical properties were measured across the gradient by nanoindentation. Certain alloys in the non-equiatomic system exhibited improved mechanical properties in comparison to the equiatomic counterpart. Bulk specimens of candidate alloys from the non-equiatomic system were prepared by arc melting, and tension tests were performed with a custom-built micro-specimen testing system. High-temperature mechanical testing was also conducted using a Gleeble thermo-mechanical simulator. |
