Sažetak
Understanding and control of chemical composition is one of the most important factors for practical application of Cu-Al-Mn shape memory alloys [1]. Microstructure and phase transformation temperatures of Cu-Al-Mn alloys are very sensitive on content of components and even slightly changes can significantly shift transformation temperatures as well as prevent shape memory properties [2-4]. In this work, an attempt has been made to study of influence of different Al/Mn ratio on the thermodynamic properties and changes in phase transformation temperatures of Cu-Al-Mn alloys. Cu-Al-Mn specimens were prepared by melting in the electric-arc furnace and casted in the cylindrical moulds with =6mm. Alloys were homogenised at different temperatures and quenched in the water. Microstructure of as-cast state and heat-treated state of Cu-Al-Mn were followed by optical microscopy and scanning electron microscopy. The influence of alloy content on the transformation temperatures was carried out by simultaneous thermal analysis, STA DSC/TG.
