Abstract
In this study, a heterogeneous microstructure was developed in commercially pure magnesium using traditional blend-press-sinter powder metallurgy process, followed by hot extrusion process. Microstructure and mechanical properties were studied on sintered and extruded samples. Microstructural characterization revealed distinct large grain domains surrounded by fine grain domains in the sintered samples; the pattern was preserved in the extruded samples with substantial grain refinement. Mechanical properties’ characterization revealed reasonably good hardness values for the heterogeneous magnesium, which significantly improved due to the extrusion process. It also revealed that heterogeneous magnesium possessed high strength and remarkable ductility in the sintered samples, which reached an extraordinarily high level in the extruded samples.
