摘要	High-cycle fatigue (HCF) and low-cycle fatigue (LCF) properties of a rolled AZ31-O alloy along different directions were evaluated at room temperature. Two types of samples denoted as RD (rolling direction) and TD (transverse direction) were compared because the samples along the two typical directions show an obvious anisotropy. By evaluating the fatigue parameters following the Manson-Coffin and Basquin's equations, it is found that the fatigue lives of TD samples are longer than those of RD samples under both stress-controlled and strain-controlled cyclic loadings. Finally, the microscopic and macroscopic fracture features under tensile and fatigue loadings are observed and compared with the available literatures. (C) 2010 Elsevier Ltd. All rights reserved.
