The paper examines the conceptual possibilities of using intelligent materials capable of simultaneously performing the functions of actuators and state-change sensors. As such elements, it is proposed to use nanostructured ferromagnetic alloys with shape memory based on multicomponent copper compounds. A comparative analysis of the inelastic deformation behaviour of CuAlMn(Fe) alloys obtained by various methods with known analogues is carried out, which indicates the potential possibilities of their use in deformation devices of restorative action. On the massive polycrystalline CuAlMn(Fe) samples, morphological and kinetic features are revealed, when martensitic transformations are induced, which are associated with a change in the magnetic state because of the appearance of the induced anisotropy of the shape and directly depend on the proposed thermomagnetic treatment. The electrical and magnetic characteristics of the selected compounds are studied. Unlike CuAlMn alloys, CuAlMnFe alloys almost do not change the specific magnetization with temperature and time of low-temperature annealing that is due to the predominance of antiferromagnetic ordering over ferromagnetic. Based on the obtained properties of nanostructured CuAlMnFe alloys, a conclusion is made regarding the possibilities of their use as smart materials for various purposes.
