Özet

Aluminum, zinc, magnesium, copper and silicon carbide powders were alloyed by mechanical alloying (MA) at certain ratios and for different periods. At the same time, the zinc effect on the microstructure was investigated by keeping the ratio of zinc in the mixture at different ratios for each mixture. X-ray diffraction (XRD) analysis was carried out to investigate the different phases. Analyzes of the microstructures of alloys with different alloying times were investigated by scanning electron microscopy (SEM) and optical microscope. The powders obtained by the MA method sintered in an argon atmosphere, which is a protective gas, to obtain billets from the powder samples. Finally, the billets were polished and then examined under an optical microscope.
