Effects of environmental temperature and sample pre-straining on high cycle fatigue strength of WE43-T5 magnesium alloy
Source abstract
Abstract
Abstract This work investigates the effects of test temperature and sample pre-straining on the high cycle fatigue behavior of a magnesium alloy, WE43. Fatigue strength is found to deteriorate with environmental temperature from room to 100℃. In contrast to the samples pre-strained in tension, fatigue strength improves for the samples pre-strained in compression. The peak improvements of over 2x is determined for the samples pre-compressed to 6% strain. Significantly, the alloy sufficiently pre-strained in compression begins to exhibit the endurance limit. The interesting characteristics of the alloy behavior in fatigue are rationalized in terms of the microstructural evolution and deformation mechanisms.
