Abstract

The fabrication of magnesium alloy metal-matrix composites (MMCs) and the mechanical properties of the sandwich formed with this material were investigated. Magnesium alloy composites containing various volume percentage of 0.99, 2.91, 4.76 and 9.09 % silicon-carbide (SiC) particles were prepared by molten metal mixing and machined as the faceplate of the sandwich. The particle had been dispersed by the injecting of the argon gas from a stainless pipe. Optical microscopic examination, hardness and tensile test were carried out. The sandwich was combined by the hot press method and studied by bending test. It is observed that the hardness of MMCs increases, but its strength decreases with increasing volume percentage of silicon-carbide particle, according to the results of hardness and bending test. It can be found that the specific strength and specific bending strength of sandwich composites fabricated with the faceplates of magnesium alloy added SiC reinforcements are a little higher than that sandwich with the aluminum alloy faceplates, but less than that of sandwich with magnesium alloy.
