Abstract Scope |
In this study, FeNiAlCr high-entropy alloy was prepared by vacuum induction furnace which grain size is about 2-3 μm. There are two second-phases were found in the alloy: Geometric Close-Packed phase (GCP) and Topologically Close-Packed Phases (TCP). The GCP nanophase, Fe2AlCr, is distributed in the grain. The continuous TCP phase, Ni3Al phase (β phase), is formed at the grain boundary of the alloy.In this study, the formation and decomposition of the second phase in high-entropy alloys and the effect of the second phase on the properties and mechanism of the alloys are analyzed by SEM, EDS, XRD, DSC-TG, tensile test and resistivity test. |
