Microstructural and phase analysis of CuAlNi shape-memory alloy after continuous castingGojić, Mirko (Avtor) Kožuh, Stjepan (Avtor) Anžel, Ivan (Avtor) Lojen, Gorazd (Avtor) Ivanić, Ivana (Avtor) Kosec, Borut (Avtor) , Inštitut za kovinske materiale in tehnologije (Lastnik avtorskih pravic) shape memory alloysmartensitecontinuous castinggrain sizeThe results of the characterization of a CuAlNi shape-memory alloy after continuous casting technology are shown. Using this procedure a bar with a diameter of 8 mm was manufactured. After solidification of the alloy the microstructure characterization was carried out using optic microscopy (OM), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) methods. Our results showed that the as-cast alloy consisted of the parent β1 and β1’ martensite phases. The martensite phase primary as the needle-like inside grains was observed. Martensite laths have different orientations inside particular grains. It was found that the average grains size is 98.78 µm. The grain diameter near to the external surface is higher than in the center. The average hardness of the alloy was 275 HV1.20132017-03-16 15:46:35Znanstveno delo65197sl
