Analysis of Cu-Al-Mn shape memory alloys after casting in moulds

Shape memory alloys (SMAs) are advanced functional materials suitable for technical applications. Among them Cu-Al-Mn alloy is a promising candidate for industry applications (mechanical engineering, electro-engineering etc.) due to their ductility. In this work analysis of the Cu-Al-Mn alloy after smelting and casting in the laboratory electro-arc furnace is shown. Metallographic analysis of the alloy samples were carried out by an optical microscopy and scanning electron microscopy including energy dispersive spectroscopy. It was found that after casting two-phase microstructure occurred. Grain size of phases and hardness of alloy after smelting and casting are similar. Martensite microstructure and secondary particles are not observed.
