The effects of cooling condition on high cycle fatigue (HCF) and fatigue crack propagation (FCP) behaviors of β-processed Ti64 alloys were examined. Two different cooling rates of air cooling (β-annealing) and water quenching (β-quenching) were employed, and selected specimens were subjected to stabilization annealing. No notable microstructural changes were observed for the β-annealed Ti64 alloys with stabilization annealing. However, it was found that effect of stabilization annealing on the FCP behavior of β-quenched Ti64 alloys appeared to be related to the built-up of residual stress after quenching. In this talk, the mechanical behavior of β-processed Ti64 alloys with and with stabilization annealing will be presented based on the micrographic examination, including crack growth path and crack nucleation site, and fractographic analysis.
