The studies on fabricating techniques and development status of particulate reinforced magnesium matrix composites were reviewed, and a few kinds of fabricating techniques were emphasized, such as Powder Metallurgy, Compo-casting and In-situ Reaction Synthesis. Merits and demerits of those fabricating techniques were commented. At last, It puts forward personal idea and prospect about development of particulate reinforced magnesium matrix composites. The author proposed that Semisolid Stirring was suitable technique for industrial production and In-situ Reaction Synthesis was the most promising technique in further study and application.
