Phase Investigations of Copper Based CuZn38Al2MnFe Alloy
In the work phase investigations of special brass CuZn38Al2MnFe alloy are presented. The microstructure, chemical composition and phase identification of the investigated alloy were examined using scanning electron microscopy (Philips 30/ESEM), light microscopy Leica coupled with PC computer with installed MultiScan program, energy dispersive X-ray spectroscopy (EDX) and X-ray diffractometry (XRD), respectively. The investigation of volume fraction existing phases was carried out using image analysis. It was found in the test bend that presence of Fe4Mn77Si19 phase in microstructure caused an increase of brittleness of the tested alloy.
