Thermal analysis and microstructural investigation of Cu-rich alloys in the Cu-Al-Ag system

Copper rich region in shape memory Cu-Al-Ag system was experimentally investigated using DTA and calculated using optimized thermodynamic parameters according to CALPHAD method. Overall composition alloys were chosen along three vertical sections with constant copper content of 70, 80 and 90 at%. Experimentally determined solidus and liquidus temperatures were compared with the results of thermodynamic calculation and good mutual agreement was noticed.
