Abstract (english)
In this paper the results of thermal and microstructural analysis of CuAlNi shape memory alloy before and after heat treatment were presented. The bar of the Cu-12.8 Al – 4.1 Ni (wt.%) alloy obtained by vertical continuous casting technique after casting was submerged to a certain heat treatment procedure. The solution annealing at 850 °C was performed, holding on that temperature for 60 minutes and following water quenching. Afterwards, the tempering at four different temperatures (150 °C, 200 °C, 250 °C and 300 °C) was performed. The microstructural results were obtained by optical and scanning electron microscopy. Thermodynamic calculation of ternary Cu-Al-Ni system under equilibrium is performed by software Thermo-Calc 5. Phase transformation temperatures were determined by differential scanning calorimetry (DSC). The DSC results show the highest values of transformation temperatures in as-cast state. After solution annealing and tempering the transformation temperatures show lower values with exceptional stability of Ms temperature (martensite start temperature).
