摘要：
This article presents the high-cycle fatigue behavior of an as-forged-T5 Mg-Zn-Y-Zr alloy with stress ratios of R=-1 and R=0.1 at ambient temperature. The relationship between the maximum stress and the number of cycles to failure is established. The fatigue strength of the alloy at 10(7) cycles is strongly affected by both the heat treatment and the mean applied stress. (c) 2007 Elsevier B.V. All rights reserved.
