Sažetak
Shape memory alloys (SMAs) are a relatively new advanced functional metallic materials used in different industrial fields. Among them CuAlMn alloys can be used due to their ductility. In this work the results of microstructural and dynamic- mechanical properties of Cu-8.3Al-9.4Mn (wt. %) alloy after casting and plastic deformation are presented. After cold rolling of strip the solution annealing at 900 °C holdnig for 30 minutes following water quenching was carried out. Metallographic analysis of the alloy was carried out by an optical microscopy (OM) and scanning electron microscopy (SEM) equipped by device for energy dispersive spectroscopy (EDS). Damping properties of the alloy were carried out by dynamic-mechanical analyzer (DMA) method. It was found that after casting and hot+cold rolling two- phase (alpha+beta) microstructure existed, while after quenching of the strip only martensite microstructure occurred. Dynamic-mechanical analysis results confirmed large energy loss in the investigated samples, as a result of movement of interfaces of martesite structure.
