Sažetak
In this work the mechanical properties, microstructures and fracture surfaces of Cu-Al- Mn shape memory alloy after casting and quenching were investigated. The bars with diameter of 8 mm were produced by continuous casting technique. Quenching of samples was carried out from 900 °C/30 minutes, followed cooling in room temperature water. After casting and heat treatment the tensile strength, elongation, reduction in area and hardness were tested. The microstructure characterization of samples was carried out by optical microscopy (OM) and scanning electron microscopy (SEM) along with EDS analysis. The fracture surfaces were tested by SEM. After continuous casting the Cu-Al-Mn alloy show tensile strength of 627.5 MPa, elongation of 8.5 % and reduction in area of 17.9 %. The partly martensite microstructure was found after casting, while after quenching the microstructure is completely martensite. Quenching of samples resulted by decreasing of mechanical properties (expecially reduction in area) and change in morphology of fracture.
