Abstract

The mechanical properties and microstructural evolution of a medium-entropy alloy Co_17.5Cr_12.5Fe₅₅Ni₁₀Mo₅ (at%) in a low temperature range (including the record low temperatures region down to 0.5 K) were investigated. It has been established that low-temperature plastic deformation initiates martensitic phase transformations in this alloy, and the values of the dynamic modulus of elasticity correlate with the degree of phase transformations.
