Investigation of Microstructure of Aluminum Based Composite Material Obtained by Mechanical Alloying

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.

Automated summary

The study improved aluminum alloys through mechanical alloying and investigated the effects of zinc on the microstructure. Analysis of alloys with different alloying times was conducted using various methods, leading to the production of high-quality aluminum alloy billets.
