Sažetak
Cu-Al-Mn and Cu-Al-Mn-X alloys are highly investigated in past years, due to their multifunctional properties, shape memory properties, excellent ductility and good cold workability. [1, 2] Cu-Al-Mn alloys are the most used as stents and actuators, although they have wide application also in other areas. [3, 4] Manganese is the key element for -phase stabilization, which is the parent phase for martensitic formation during rapid cooling. Small changes in aluminium and manganese content in alloys cause differences in transformation temperatures and final properties. In this paper, the influence of aluminium and manganese content as well as processing parameters is investigated. Cu-Al-Mn specimens were prepared by electric-arc furnace, under argon atmosphere and casted in cylindrical moulds, with diameter of 8 mm. After grinding, polishing and etching specimens were characterized by optical and scanning electron microscopy. Thermodynamic calculations were performed by Thermo-Calc software and phase transformation temperatures were obtained by simultaneous thermal analyzer. Experimental results were correlated with theoretically predicted temperatures.
