Abstract: Refined grain morphologies influence the mechanical properties of Ti-6Al-4V alloys. This work investigated the effects of adding different concentration of boron on the microstructural and hardness properties in as-cast and heat treated Ti-6Al-4V alloy. The alloys were prepared using laboratory arc furnace in inert gas atmosphere. XRD indexed patterns of samples were in agreement with established Ti-B binary phase diagram. SEM micrographs of samples showed reduced grain size in boron added samples. STA treatment resulted in higher hardness. Microstructures of the samples at different levels of boron (1.0, 1.64 and 2.0 wt%) were also compared.
