摘要: In recent years, ultrafine grained (UFG) materials have received a great deal of attention, as they exhibit superior combinations high strength and enhanced ductility compared to conventional large alloys, c.f. Valiev et al. [1], Love [2]. Until recently, most studies that focused on rate sensitivity work hardening behavior UFG at different strain rates were conducted under monotonic test conditions, e.g. Wang Ma [3] Li [4]. However, for many the envisaged structural applications these materials, cyclic properties their dependence loading parameters will be key issue.
