Pre Homogenization Clay

Effect of Pre-homogenization Treatment on Microstructure, …

This paper studied the microstructure, mechanical properties, and corrosion resistance of AZ61 magnesium (Mg) alloy with and without homogenization treatment before extrusion. After homogenization treatment, the size of the second phase decreases, resulting in a more uniform microstructure of the extruded sample. Compared to the as-extruded sample, …
