摘要

Using cold rolling and low temperature annealing, a Fe₆₅Ni₁₅Cr₁₀Co₁₀ medium entropy alloy (MEA) with a heterogeneous microstructure was presented. The cold rolled and low temperature annealed specimen display an abnormally ultrahigh yield strength and ductility at −196 °C, compared to the cold rolled specimen. The underlying mechanism are mainly attributed to a synergy of hetero-deformation induced (HDI) strengthening, boundary strengthening and transformation-induced plasticity (TRIP) effect.
