Sažetak
In this paper the results of microstructure and hardness of CuAlNi and CuAlNiMn shape memory as- casted state alloys is presented. Melting of the alloys was carried out in vacuum induction furnace in protective atmosphere of argon. Alloys were casted into ingots with 15 kg weight. Microstructural characterization was obtained by optical microscopy (OM) method and scanning electron microscopy (SEM) method equipped with energy dispersive spectrometry (EDS). Partially martensitic microstructure in CuAlNiMn alloy was observed, while the two phase microstructure in CuAlNi alloy was found. A hardness measurement was performed by Vickers method. Hardness of CuAlNiMn alloy was 333 HV 0, 5 and CuAlNi alloy was 475 HV 0, 5.
