The main purpose of this study is an in-situ synthesis of (TiB+TiC) hybrid titanium matrix composites (TMCs) by vacuum induction melting method and to verify its mechanical properties.The melting route was adopted to synthesize the commercial pure titanium (cp Ti) and granular boron carbide (B_4C).The reinforcements,the fraction of 10 vol.pct,were formed by adding 1.88 wt pct B_4C to cp Ti.After in-situ synthesis of TMCs,electron probe micro-analysis elemental mapping was carried out to confirm the distribution and shape of reinforcements.The cone-on-disk type sliding wear test was also done for the identification of TMCs.It is concluded that (TiB+TiC) hybrid TMCs can be in-situ synthesized and has better wear properties than H13.
