Exploring and using shape memory materials

A brief overview of the production and application of materials with shape memory effect is given. Data are given, the emergence of such a concept as the shape memory effect in general, as well as data on the first studies of materials with a shape memory effect (SME), data indicating the absence of hardening of the process of accumulation of deformations of direct martensitic transformation in shape memory alloys. It is told about the occurrence of internal stresses, tending to return the structure to its original state. The advantages and uniqueness of these alloys are shown. The shape memory effect of metals is associated with special types of deformation - martensitic transformations. How does martensitic transformation depend on temperature Also, most shape memory alloys most often contain alloys of copper, aluminum and nickel, as well as nickel and titanium. Widespread use of such materials in various spheres of life. The characteristics of the effect of shape memory and reversible shape memory are considered. The implementation of mechanisms with the memory shape effect is analyzed. The range of applications of these materials is growing day by day and promises many more interesting things. Shape memory materials are the materials of the future.
