摘要：

The structure-phase features and mechanical properties of the Cu-14 wt % Al-4 wt % Ni alloy, which undergoes thermoelastic martensitic transformations and exhibits shape memory effects associated with them, have been studied for the first time in a wide temperature interval. Scanning and transmission electron microscopy and X-ray phase analysis were used in this study. The uniaxial compressive strain arrangement was used in isothermal measurements of the mechanical properties.
