Remarkable increase in high-cycle fatigue resistance in a titanium alloy with a fully lamellar microstructure
Source abstract
Abstract
Abstract The high-cycle fatigues of a fully lamellar microstructure (FLM) and commercial material (TCM) in a titanium alloy were comparatively investigated. Significant increase in the fatigue property was observed in FLM compared with TCM. The underlying microstructure below the facet was obtained by using electron backscatter diffraction. A severe crack was observed to nucleate at the primary α/β interface due to a high strain concentration of TCM, while slip transmission, kink band and nanotwins were prevalent and beneficial to producing a uniform strain distribution with FLM. Dislocation interactions between the lamellar α caused the facet crack initiation at α colony boundaries.
