A new titanium based alloy, Ti- 1 oTa- 1 oNb, has designed to examine the improved mechanical properties and biocompatibility. A specimen oftitanium alloy was melted in a consumable vacuum arc furnace and homogenized at 105oC for 24 h. The effect of hot rolling on microstructure was estimated after rolling at 40(?C and 800°C respectively. Surface ofmelted alloy by consumable vacuum arc melting was consisted ofrough surface and it was changed to sound surface by coating ofZrQ slurry on copper mold surface. The hardness of Ti-1oTa- 1 oNb alloy increased with the amount ofoc + [3 phase. Ti-loTa-loNb alloy showed Widmansfzi ten stmcture by hot rolling at 800°C and in the rolling fl-region was negligible effects on microstructure refining.
