3 1

Abstract

The paper presents the results of studies on the development of alloys with shape memory effect (SME) based on the NiTiCu system using the high-energy powder milling method. The aim of the study is to obtain microstructured materials with improved functional properties, such as high temperature stability, low phase transition hysteresis and increased cyclic durability. The high-energy milling method allows achieving a uniform distribution of components and the formation of a micro-sized structure, which contributes to the optimization of phase transformations and improvement of the mechanical properties of the alloys. The influence of milling parameters, such as processing time and impact energy, on the microstructure, phase composition and functional properties of the obtained materials were studied. The results demonstrate the promise of using high-energy milling to create NiTiCu alloys with improved performance characteristics, which opens up new possibilities for their application.
