Sažetak
Shape memory alloys are relatively a new class of advanced functional materials. The shape memory effect in these alloys is the remembrance of the previously introduced material shape, and in physical aspect it is the consequence of martensite phase transformation. The three most popular polycristalline shape memory alloys are: Ni-Ti (nitinol), Cu-based (Cu-Zn-Al, Cu-Al-Ni etc.) and ferrous alloys (Fe-Pt, Fe-Mn-Si, etc.). In this work the results of microstructural analysis of CuAlMn alloy after continuous casting at three different casting speeds are shown. Microstructural analysis was carried out by means of optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The large grains in microstructure were observed. The martensite phase primary as the needle-like into grains only sporadically was observed on the sample casted with the highest casting speed. In view of the chemical composition the large heterogeneity in microstructure was observed.
