Structure and properties of a ribbon quenched from a molten Mn−Cu−Cr alloy with reversible shape memory

Alloys based on the Mn-Cu system with a martensitic f.c.c.[arrow right]f.c.t. transformation are typical representatives of materials with a reversible shape memory effect. Plastically deformed in a martensite state, specimens of these alloys reversibly change their shape in repeated cooling and heating. The attained values of reversible (^sub rev^) and specific reversible (d^sub rev^/dt) thermodeformation, the very slight hysteresis of thermodeformation in thermocycling, and the possibility of a wide variation in the temperature range of the highest thermosensitivity by alloying and heat treatment make Mn-Cu-base alloys a promising material for thermoregulators used in various fields of engineering.[PUBLICATION ABSTRACT]
