This paper reviews the manufacturing of magnesium-based alloys prepared by powder metallurgy (PM) technique and analysis of the effects of PM parameter on the developed microstructure, texture and mechanical properties. Powder metallurgy (PM) technique has been considered to produce magnesium product with consideration of less complex, finer grain and improved mechanical properties. Selection of PM route especially sintering to full densification determines a good diffusion path of alloy for interparticle bonding. This paper discusses the preparation and process parameter of each process in powder metallurgy routes, and the evolved microstructure including the crystallography texture and mechanical properties of the magnesium-based alloy product.
