Abstract

Abstract: Effects of cold rolling, annealing and aging on the microstructure and mechanical properties of the Fe₅₀Ni₂₅Cr₁₅Al₁₀ high entropy alloy were investigated. The results show that the as-cast Fe₅₀Ni₂₅Cr₁₅Al₁₀ high entropy alloy has FCC+B2 bi-phase structure. After cold rolling, annealing and aging, the FCC phase is transformed from dendrite to equiaxial grains, the annealing twins accounting for 43.7% are produced, and the average grain size is refined from 228.84 μm to 4.51 μm. The B2 phase exhibits two precipitation modes, namely chain like large-sized intergranular precipitated phase and small-sized ellipsoidal phase dispersing inside the grains, and the proportion of B2 phase increases from 0.9% to 13.3%. The yield strength and tensile strength of the high entropy alloy are increased from 254 MPa and 528 MPa to 466 MPa and 760 MPa, respectively, and the percentage total extension at fracture is 31.5%, showing good strength-plasticity matching.
