Paper Title:
Processing, Microstructure and Mechanical Properties of SiCp/AZ91 Mg Matrix Composites Fabricated by Squeeze Casting
  Abstract

The fabrication processing, mechanical properties and fracture characters of SiCp/AZ91 magnesium matrix composites fabricated by squeeze casting were investigated. The SiC particles with different diameters (5μm, 20μm and 50μm) were employed as the reinforcement in the composites, the volume fraction of them was 50% in all cases. Experimental results showed that when the size of SiC particle decreased, the tensile properties of the composite increased. The tensile properties of SiCp/AZ91 composite with small particles are controlled by the properties of matrix alloy and the strength of the interface between the matrix and reinforcements, but the composites reinforced by large particles are controlled by the fracture of the particles.
