Sažetak
In this paper microscopy analysis (optical microscopy, scanning electron microscpy and energy dispersion spectrometry) and hardness testing of Cu-9Al-7Mn alloy microalloyed with titanium (0.4 wt.%) were carried out. Analysis was performed in as-cast state and after heat treatment (900 °C/30 min/H2O). Alloy was prepared from pure metals in vacum electroarc furnace under the protective argon atmosphere. The heat treatment and metalographic preparation were performed after casting. Optical and scanning electron microscopy (SEM) with energy dispesion spetrometry (EDS) were used for microstructural analysis. For microhardness of samples in as-cast and as- quenched state Vickers method was used. In the as- casted sample martensite phase was not detected, while after heat treatment martensite phase was detected. Phase transformation temperatures were not visible on the DSC curve measured from room temperature to 300 °C. After heat treatment significant increase in microhardness of analyzed alloy was observed.
