摘要：

In this study, fatigue crack initiation and propagation behavior of magnesium alloy AZ31 within a crystal grain near the fatigue limit were investigated in detail using a scanning probe microscope (SPM). At a stress amplitude slightly higher than the fatigue limit, cracks are arrested by the grain boundary for an extended period. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd.
