摘要：

TiB2 reinforced in-situ titanium aluminide matrix composite was made through reaction synthesis process using high purity elemental powders of Ti, Al, Cr, Nb and B. XRD of the synthesized block showed presence of mainly Al3Ti and TiB2 phases. To obtain. Ti aluminide based matrix, the material was homogenized in two phase region (alpha(2)+gamma). Presence of gamma phase matrix alongwith alpha(2) was confirmed through XRD, SEM and TEM. Uniform distribution of TiB2 phase was confirmed through elemental mapping and by analyzing specimens of different locations. Differential scanning calorimetry of powder mixture showed presence of endothermic peak for Al melting and exothermic peak of Ti aluminide and TiB2 formation.
