The microstructure and tensile deformation of a number of sintered TiB2-reinforced near-titanium aluminide matrix composites have been studied. When TiB2 was added to the microstructures via spark plasma sintering processing at values of 0.5 and 3.0 vol pct, it was contrasted with unreinforced TiAl. For every composition and reinforcement variety, the effects of temperature and time have been examined. Within the studied composites, a range of TiB2 sizes was measured. TiB2's elastic moduli, tensile strengths at ambient temperature, and overall strain-hardening response all rise as the volume fraction of TiB2 increases. According to the findings, both indirect and direct sources contribute to the strengthening and flow behaviour of these composite materials. Strengthening contributions are indirectly derived from the microstructural changes within the matrix of the composite.
