Full-life growth behavior of a naturally initiated internal fatigue crack in beta titanium alloy via in situ synchrotron radiation multiscale tomography
Source abstract
Abstract
The full-life growth behaviors of an internal fatigue crack in a beta titanium alloy were non-destructively monitored using in situ synchrotron radiation multiscale computed tomography. The crack fronts at various cycles were superimposed on the fracture surface from the perspective of crack growth stages. The crack propagation process consisted of multiple facets formation and subsequent growth into the matrix and was dominated by the former process. The crack opening and blunting behaviors triggered crack growth from the facets to the surrounding matrix. The overall crack propagation rate of the internal crack was revealed to be slower than the surface crack.
