A new molten metal mixing process, RCM (Rotation-Cylinder Method) for incorporating reinforcement particles into molten magnesium, has been developed for manufacturing SiC particle reinforced magnesium composites in an ambient atmosphere. The RCM can be characterized by the U-shaped laminar melt surface with the Rankine vortex, which significantly reduces particle agglomeration and entrapped slags, such that composites of improved microstructure and properties can be manufactured successfully in conjunction with the subsequent fabrication processes. The RCM can incorporate SiC particles (5 Jam size and larger) into molten magnesium with particle volume fractions of up to 20 vol.%. In this paper, the development background, the characteristic vortical motions, the optimum manufacturing conditions and the in-process wetting procedures of the RCM are described.
