The research aimed on creating shape memory nanocomposites based on copper alloys are due to their complex of mechanical and magnetic properties. Deformation effects in such functional materials that occur when exposed to temperature, magnetic field or mechanical stress allow the use of them as sensors or actuators that artificially cause action when the control signal is fed.
The precipitation of nanosized particles during the alloy aging is a promising approach to the creation of a new class of high-strength functional materials. Nanoparticles produced by dispersion hardening do not undergo martensitic transformation, but due to variation in their chemical composition, size and volume fraction it is possible to control simultaneously the mechanical and functional properties of the material and, thus, to obtain nanocomposites with the necessary complex of service properties [1, 2]. 
This paper presents the study of deformation behavior of nanocomposite based on Cu alloy under the influence of temperature and mechanical stress.
