The elevated temperature tensile experiments have been carried out on the magnesium alloy and results indicate that the magnesium alloy has excellent superplastic property.Gleebe-1500 testing machine was used in the diffusion bonding experiment on the superplastic magnesium alloy.Then,the shear stength of the joints under different conditions is obtained through shear testing and the optimum processing parameters for the diffusion bonding are achieved.By metallurgical microscope and scanning electron microscope (SEM),it is revealed that the micromechanism of diffusion bonding is the slide of grain boundaries caused by the growth of grains and atom diffusion of the superplastic magnesium alloy. 相似文献

Variation of hydrogen level in magnesium alloy melt 总被引:4,自引:0,他引:4
M agnesium alloy is one of the lightest metals used in industry. It offers numerous merits in physical, mechanical and casting properties: high specific strength and stiffness, good castability suitable for high pressure die casting, low density, high damping capacity, good thermal and electrical conductivity etc. [1] However, microporosity in the castings reduces mechanical properties [2-4] such as ultimate strength, yield strength, ductility and fatigue resistance. There are mainly two viewp… 相似文献
