摘要：
85.67 wt.% Cu-9.9 wt.% Al-4.43 wt.% Ni shape memory alloy has been studied. Polycrystalline specimens have been quenched, into water, after heat treatment at high temperature and followed by two successive runs from room temperature to 923 K and inversely. The microstructural and thermodynamic studies presented in this work have been performed using DSC (Differential Scanning Calorimetry), X-ray diffraction analysis at a variable temperature and TEM (Transmission Electron Microscopy) analysis. Stable phase precipitation of AlNi type was observed to appear in this alloy.
