摘要：

The variation of microstructure of rapidly solidified Al-Fe-V-Si-Nd nanocrystalline alloy ribbon during low-cycles fatigue was studied by TEM and PAT (positron annihilation technology). G-P zones appear and grow with the increase of cycles. After 1500 cycles, the G-P zones grow continuously with the increase of cycles when the zone size is larger than the critical size and G-P zones dissolve again when the zone size is smaller than the critical size.
