The paper presents comparison of microstructure and hardness of Cu-Al-Ni shape memory alloy before and after heat treatment (quenching at 900°C/60 min/water and tempering at 300°C/60 min/water). Microstructural analysis was obtained by optical microscopy (OM) and scanning electron microscopy (SEM) equipped with energy dispersive spectrometr...
