Abstract

Cu-based shape memory alloys are increasingly used instead of nitinol alloys, due to their low price, good shape memory effect and superelasticity. In this work, Cu-Al-Mn alloys with different content of aluminium were investigated. Alloys were melted in the electric-arc furnace and casted in the cylindrical moulds as well as continuous casted. Microstructure of prepared samples was followed by scanning electron microscopy and phase transformations were determined by DSC analysis.
