Description beta-Titanium alloys form one of the most versatile classes of structural materials due to their high specific strength, good hardenability, crack propagation resistance and substantial ductility. beta-Titanium alloy with a composition (in wt%) of Ti-5Al-5Mo-5V-1Cr-1Fe was processed by double vacuum arc remelting route. In the present work, the effect of boron addition (up to 0.12 wt%) on the as-cast microstructure and beta-transus (T-beta) of the alloy was studied using characterization tools like optical microscopy, electron back scattered diffraction, scanning electron microscopy, differential scanning calorimetry (DSC) and dilatometry. It was observed that boron addition has resulted in refinement of the as-cast microstructure due to precipitation of titanium boride whiskers along the grain boundaries. The DSC and dilatometry studies on the as-cast alloy revealed significant effect of boron addition on thermal stability of the alloy.
