Effect of Pre-homogenization Treatment on Microstructure, Mechanical Properties, and Corrosion Resistance of Hot Extruded AZ61 Magnesium Alloy

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, the yield strength (176.04 MPa) and tensile strength (266.3 MPa) of the homogenization-extruded samples were higher than those of the as-extruded samples, and the elongation after pre-homogenization treatment is 16.1
