Outline of Final Research Achievements

Oxygen is generally treated as the impurity element in Ti and Ti alloy. However, oxygen can be expected as alloy element for Ti and Ti alloy because the solute strengthening capability is much high. In this study, the microstructure, tensile property, and deformation mode in Ti with high oxygen content were evaluated. Tensile total elongation in Ti with high oxygen content shows good ductility by texture control. This study suggests that it would be possible to use high oxygen solute Ti as alloy element.
