Sažetak
Copper based Cu-Al-Mn alloys are intensively studied due to their high stability, very good ductility and excellent cold-workability [1-2]. Higher ductility and elongation of material are consequence of parent phase with L21 structure that has a lower degree of order at concentration of aluminium less than 18 % at. [3]. During cooling, the disordered -phase transforms in the (A2)2(B2)1(L21) ordered phase[4]. In this work, Cu-Al-Mn alloys with various chemical compositions were produced by melting of pure metals in the electric-arc furnace. Thermodynamic calculation of phase diagram for equilibrate conditions was done by Thermo-Calc 5 software. Microstructure analysis of as-cast state of prepared specimens was performed by optical microscopy and scanning electron microscopy, respectively. The characteristic transformation temperatures were determined by simultaneous thermal analysis DSC/TG, in two heating/cooling cycles from 25 to 1300 °C. Phase identification of fabricated alloys was carried out by means of X- ray diffraction analysis.
