The effect of hydrogen on the fracture toughness of oxygen-strengthened titaniumStudies of oxygen-strengthened titanium alloys have indicated that while hydrogen has little effect on tensile properties, it causes a marked decrease in impact strength. It is presently established experimentally that the presence of hydrogen has essentially no effect on the fracture-toughness factor at the onset of crack propagation, in commercial-grade titanium alloys containing either low or high concentrations of oxygen. These findings are congruent with other study results on the tensile properties of these alloys, but contrast with the previously noted pronounced effect of hydrogen on impact resistance.
