Sažetak
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 spectrometry (EDS). Before heat treatment (casted and forged state) the sample has a partially martensitic microstructure with presence of γ2 phase, while on samples after the heat treatment completely martensitic microstructure with inclusions of complex chemical composition was observed. These inclusions can have a potential unwanted influence on alloys properties. Hardness of the alloy before heat treatment was 344.3 HV0.5, after quenching was 229.6 HV0.5 and after tempering was 300.2 HV0.5.
