Titanium and his alloys can solve high amounts of oxygen, which generally worsen mechanical properties. This paper compares energy dispersive X-ray analysis, three-dimensional-atom-probe and carrier-gas-hot-extraction as techniques in order to quantify the oxygen content in commercial grade titanium alloys. Assets and drawbacks of the techniques are pointed out. Oxygen enrichment by machining processes is verified in the drill hole of automotive connecting rod.
