摘要：

The effect of gamma '-phase dispersed particles on the temperature dependence of the stresses of the start of martensitic transformations sigma(cr)(T), the shape memory effect, and the superelasticity is investigated depending on aging conditions in the [001]-oriented crystals of the non-equiatomic Fe - 28% Ni - 17% Co - 1.5% Al - 2.5% Ti (at.%) high-entropy alloy under tension/compression. It is shown that sigma(cr)(T) during the gamma-alpha ' stressinduced martensitic transformations is independent of the strain method (tension/compression) for small gamma '- phase particles with sizes d <= 4-6 nm. The value of the reversible strain at tension is 3.5-4.5%, and it is 1.5% at compression. Reasons for strong dependences of the reversible strain and the mechanical hysteresis on the strain method (tension/compression) and particle sizes are discussed.
