A new method to in situ fabricate magnesium alloy reinforced with 8 wt % of TiB2 and TiC is described. The XRD result revealed the formation of TiB2 and TiC in master alloy magnesium matrix composites. Uniform distribution of fine reinforcement in the matrix material obtained through microstructural characterization. Mechanical characterization revealed that the presence of TiB2 and TiC leads to an increase on microhardness and tensile strength of magnesium matrix composites. Scanning electronic micrographs taken from the tensile fracture surface of magnesium matrix composites revealed typical brittle fracture.
