摘要：

The effects of oxygen on the mechanical properties and the lattice strain of commercial pure CP) Ti and Ti-6Al-4V alloys are discussed here in terms of the Vickers hardness, tensile strength and elongation. The Vickers hardness and tensile strength of the CP Ti and the Ti-6Al-4V alloys increased with an increase in the oxygen concentration. On the other hand, the elongation of the CP Ti decreased considerably as the oxygen concentration increased, while that of the Ti-6Al-4V alloys gradually decreased as the oxygen concentration increased. Thus, the oxygen concentration has a greater effect on the mechanical properties of CP Ti compared to its effects on the Ti-6Al-4V alloy. This can be explained in terms of the difference in the solid solution effect of oxygen between the CP Ti and the Ti-6Al-4V alloy. Where, the mechanical properties of Ti-6Al-4V alloy were previously affected by an earlier lattice expansion caused by an increment in the c/a ratio of the Ti-6Al-4V during the Al and V alloying process.
