| 摘 要： | The influence of cryogenic treatment on the mechanical properties of the extruded Mg-Gd-Y-Zr（Mn） alloys was investigated by the tensile tests, scanning electron microscopy（SEM）, transmission electron microscopy（TEM）, and energy dispersive X-ray spectroscopy （EDS）. The results show that the mechanical properties of both alloys are improved greatly during the in situ tensile test by soaking the samples in liquid nitrogen for 10 min. The ultimate tensile strength, yield tensile strength and elongation of cryogenic treated magnesium alloy added with zirconium or manganese are largely elevated. And remarkable microstructure change is observed in both alloys by cryogenic treatment. There are a large number of twins, rod-like, tree-like and chrysanthemum-like precipitated phases in the microstructures and the fracture surfaces exhibit the characteristics of ductile rupture when they are observed at room temperature.
