In this study, the high cycle fatigue (HCF) performance of the extruded Mg-Gd-Y-Zn-Mn alloy reinforced by Long-period stacking ordered (LPSO) phase was researched. The results show that the Mg alloy enhanced by LPSO phase can have higher HCF strength, because the LPSO phase can effectively hindering the fatigue crack growth by force them to change the growth direction both in the high cycle tensile fatigue tests and rotating bending fatigue tests whether in smooth surfaces and V-notched samples. The fatigue strength of the smooth surface in this study can exceed 220 Mpa, which is close to the fatigue strength of Al alloy.
