Through microstructure analysis and tensile tests at room and high temperature,the microstructure and mechanical properties of magnesium alloy AZ81 with 1%～4%(mass fraction)Gd addition were studied.The results show that proper content of rare earth element Gd addition can refine the grain size,and...
Pure magnesium is mainly used as an alloying element in aluminum, for steel desulfurization, production of nodular cast iron, as a reducing agent in titanium and zirconium production, and as a chemical in various processes (see Table 1 in Magnesium Alloys: Alloy and Temper Designation System for...
The decreasing of 尾 phase improved the corrosion resistance of the magnesium alloy. The fracture mechanism of the Gd modified AM50 magnesium alloy was quasi-cleavage fracture. The corrosion residual strength(CRS) of AM50 magnesium alloy was improved after 1 wt.% Gd addition.doi:10.1016/s1002-...
The effects of rare earth elements on the microstructure and properties of magnesium alloy AZ91D alloy were studied. The different proportion of rare earth elements was added to the AZ91D and the tensile tests were carried out at different temperatures. The experimental results show that at room ...

The properties and microstructure of magnesium–6 zinc alloy and its composites were studied in this investigation. SiC particulates or short glass fibers were used as reinforcement materials with 15 volume fraction percent. The obtained materials were thermomechanically treated as follows; 60% hot extr...
High strain rate triaxial-forging(HSRTF) of AZ31 magnesium alloy was conducted by the pneumatic power hammer at 350 ℃ with a pass strain of 0.22,and the microstructure and mechanical properties of wrought alloy with the different accumulated strains was studied.The results show that the microstruc...
