Ti-48.0Al-1.3Fe-1.1V-0.30B(mol%) has been developed to improve creep properties.<sup>1)</sup> In order for this alloy to be widely employed in structural materials, it is important to understand effects of the surface finishing on mechanical properties. The finishing, such as the turning, the grinding, the beltgrinding (defined as the grinding using the endless buff-belt) of this alloy was carried out under the production scale in this study. The effects of machined surface condition on room temperature tensile properties of this alloy were investigated with metallographic characterization. The room temperature ductility was influenced by surface condition and was within the range from about 0.5 % to about 1.3 %. As a result, the improvement of ductility was attributable to removal of grain distortion at subsurface. Moreover, compared to the results of various machined specimens, the effects of chemicalmilled surface on room temperature tensile properties were also investigated.
