Two dynamic recrystallization processes in a high-performance extruded Mg94.5Y2Gd1Zn2Mn0.5 alloy

Dynamic recrystallization (DRX) associated with different second-phases in Mg94.5Y2Gd1Zn2Mn0.5 alloy during hot extrusion was investigated. Discontinuous DRX occurred along the interface of MgZn2(Y, Gd) particle and 18R LPSO phase while continuous DRX emerged in the kink bands of 14H LPSO phase. Mor...

Description
Summary:Dynamic recrystallization (DRX) associated with different second-phases in Mg94.5Y2Gd1Zn2Mn0.5 alloy during hot extrusion was investigated. Discontinuous DRX occurred along the interface of MgZn2(Y, Gd) particle and 18R LPSO phase while continuous DRX emerged in the kink bands of 14H LPSO phase. Moreover, two DRX processes enhanced the strength and ductility.
