Magnetic, electrical and mechanical properties of Fe₄₀Mn₄₀Co₁₀Cr₁₀ high entropy alloy.

ABSTRACT: A prototypical, single-phase, and non-equiatomic high entropy alloy Fe₄₀Mn₄₀Co₁₀Cr₁₀ has been mechanically deformed at room and cryogenic temperatures. Plastic deformation was accommodated via crystallographic slip at room temperature while transformation induced plasticity (TRIP) has been observed in samples deformed at 77 K. The stress-induced martensitic transformation occurred from face-centered cubic (FCC) to hexagonal close-packed (HCP) structures. A detailed electron backscatter diffraction analysis was utilized to detect phase change and evaluate the evolution of the HCP phase volume fraction as a function of plastic strain. Physical properties of undeformed and deformed samples were measured to elucidate the effect of deformation-induced
