Effect of the Temperature of Isothermal Upsetting on the Structure and the Properties of the Shape Memory Cu–14 wt % Al–4 wt % Ni Alloy

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 transmissio...

Description
Summary: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.
