Özet: | In this study, the aluminum alloys with different MgZn2 contents were prepared using the powder metallurgy method. The effect of the MgZn2 contents on the sintering density, po-rosity, microstructure and microhardness was investigated using optical microscopy, scan-ning electron microscopy (SEM), X-ray diffraction, and Vickers microhardness. The function mechanism of the intermetallic compounds formed as a result of MgZn2 addition was ana-lyzed. The results revealed that the highest sintering relative density (95.1%), lowest porosity volume fraction (4.81%), and highest hardness (112.4 HV) were observed with the 5% addi-tion of MgZn2 contents. The XRD results show that the microstructure of the bare sample (Al) is mainly composed alpha-Al phase, while, with the addition of MgZn2, the microstructure turned to have alpha-Al phase and some intermetallic compounds of Al5Mg11Zn4 and AlMg4Zn11. These intermetallic compounds were formed with higher density at the grain boundaries as white precipitates. |
