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.
