Effect of deformation and external load on the characteristics of martensite transformations and shape-memory effects in alloys based on titanium nickelide

The effect of plastic deformation and external load on the characteristics of shape-memory effects is studied for alloys based on titanium nickelide of nearly equiatomic composition. A nonmonotonic dependence of the characteristic temperatures of martensite transformations on the strain degree of deformation is obtained. This phenomenon is explained in relation to the stages of development of plastic deformation. Optimal loading and deformation conditions for obtaining maximum values of reversible deformation are determined.
