High Temperature Properties of Magnesium Based Composites Prepared by Spark Plasma Sintering

Article Preview

Abstract:

High temperature tensile test was conducted to study high temperature properties of the magnesium based composites reinforced with SiC particulates and monolithic magnesium as well. It was found that tensile strength of monolithic magnesium and Mg-SiC composites decreased with an increase in testing temperature. While the elongation to failure both samples were increased when increasing temperature. At all testing temperature, the tensile strength of the composite sample was found to be superior compared to monolithic magnesium due to presence of SiC particulates and efficiency of spark plasma sintering process in fabrication of the composites.
