Abstract

In this paper, the fracture behavior of the Ti-6242 alloy subjected to bending fatigue deformation is presented and discussed. Samples of the alloy were deformed to failure in bending over a range of maximum load levels. The macroscopic fracture mode was found to be marginally different over the range of load levels examined. Microscopically the fracture surfaces revealed features reminiscent of locally ductile and brittle mechanisms. The kinetics governing crack advance and fracture is rationalized in light of maximum load, local stress concentration effects, and contributions from intrinsic microstructural features.
