... reduction in fatigue properties can result if conventional machining operations are not carefully controlled. In addition, when welding alpha–beta titanium alloys, shielding atmospheres are required to inhibit weld contamination and the development of brittle structures. Titanium alloy driver heads...

... and is a strengthener in alpha titanium alloys (unalloyed titanium), but too much oxygen causes embrittlement of the alpha phase. The presence of an alpha case in an alpha-beta titanium alloy, such as Ti-6Al-4V, can cause a reduction in the mechanical properties of the material [ 1 ]. The potential absorption of oxygen...
