Abstract:

The use of induced magnetic field and the resultant material reaction from titanium alloys containing interstitial gas contamination was evaluated. This presentation discusses the material conductivity changes noted as evaluation of five titanium specimens was conducted. The oxygen contamination levels in the specimens ranged from 0.075 percent by weight to 0.290 percent by weight. A quantitative evaluation was conducted with difficulty due to inhomogeneity of contamination levels noted from some of the evaluated specimens. Consequently, an averaged signal response from the specimen surface was necessary. The averaged signal response corresponding to material conductivity changes was then correlated to various levels of oxygen contamination. Author
