Abstract
The effects of strain rate and test environment on the low cycle fatigue and fatigue crack propagation behavior of three TiV alloys having different deformation mechanisms were studied. The strain rate affected both the cyclic stress strain response and the fracture mode. The details of the effect depended on deformation characteristics, with the sensitivity to changes in strain rate increasing with increasing planarity of slip. All alloys exhibited longer fatigue lives at the higher strain rate. This effect was related to changes in cyclic hardening behavior and in some cases changes in fracture mode. The fatigue crack propagation resistance was also greater at the higher test frequency, with the effect being most pronounced in the vacuum environment for the higher vanadium content alloy. The results can be explained by the influence of vanadium content on the strength and deformation characteristics.
