Abstract

Alloys with the shape memory effect have recently found application in engineering. Specifically, parts made of such alloys can be actuating members in structures of thermoregulators and thermorelays. It is known that the shape memory effect is realized in alloys with a thermoelastic martensite transformation. When heated, specimens strained in a martensite state recover their initial shape partially or completely as a result of a reverse martensite transformation. If an external load is applied in thermocycling, the shape will be changed both in heating and in cooling, i.e., recovered in the reverse martensite transformation and deformed under the effect of the external load in the direct martensite transformation. This change in shape is commonly said to be reversible. The aim of the present work consists in analyzing the effect of deformation in the martensite state prior to thermocycling and of an external load during the thermocycling on the reversible change of shape in Mn−Cu-base alloys.
