Abstract Scope |
Statistical analyses of slip events for a large collection of polycrystalline materials with face-centered cubic, hexagonal close-packed and body-centered cubic structures have been performed. Relations between the yield and ultimate tensile strength, fatigue strength and the slip character are uncovered. Of main importance, the highest amplitude of the localization by slip that develops during early cycling is observed to control the fatigue life in the very high cycle fatigue regime. The locations at the grain structure scale where the highest amplitude slip localization developed are investigated. Specific grain configurations that develop during processing of metallic materials are observed to promote slip localization over a range of metallic materials. |
