摘要	Microstructural evolution during fatigue is of significance for understanding the fatigue cracking of metallic alloys. Here, we visualized amorphization near the fatigue facets for an Mg -Gd -Y -Zn -Zr alloy with long-period stacking ordered (LPSO) phase upon very high cycle fatigue (VHCF). The small amorphous patches occurred in the relatively soft nano-Mg layers, compared to the hard LPSO phase, and the amorphous band propagated along with the basal plane near the LPSO/Mg interface. This should be intimately related to the local dislocation accumulation and cumulative damage upon the cycle loading-unloading.
