Stress induced hydrogen redistribution in commercial titanium alloys

The change in hydrogen concentration as a function of applied strain has been studied in commercial titanium alloys that included threeβ-phase, twoα-phase, and an (α + β)-phase Ti-6Al-4V alloy with differingα/β morphologies.Insitu measurements were made using a nondestructive nuclear technique on samples for which uniaxial compressive and tensile stresses were applied by four-point bending.
