Abstract: Magnesium matrix in-situ composites were synthesized using commercially pure Mg ingot, coarse Ti and B4C powder as starting materials. Ti and B4C powders are mixed with zirconia balls in a plastic bottle in Ar atmosphere and the resulting mixture of these powders were compacted into a cylindrical perform. The infiltration of Mg as a matrix metal into the Ti-B4C preform by capillary forces was done under Ar atmosphere in an electric furnace for different temperatures and holding time. Samples were prepared for phase identification and microstructural investigation. The phases formed during infiltration were analyzed using X-ray diffraction technique with Cu K radiation and morphology of the structure was carried out using FESEM equipped with EDX. Different types of compounds TiC, TiB2, TiB, MgB2, MgB4, B13C2 are formed in Mg matrix during synthesis process. The dissolution of Ti and B4C is found incomplete even at the highest synthesis temperature and holding time used in this study. The relative density is found to increase with temperature and decrease with time.
