摘要：
14H LPSO phase seriously affected dynamic recrystallization (DRX) behavior of extruded Mg92Gd3Zn1Li4 alloy. After hot extrusion, extensive DRXed grains took place at kink boundaries, while only a few of DRXed grains were formed at original grain boundaries. The formation of DRXed grains near kink boundary was beneficial for mechanical properties.
