Alloy Increase

The effects of yttrium on the microstructure and mechanical properties of magnesium alloy AZ81 have been investigated by alloy preparation, microstructure analysis and tensile tests. The results show that proper content of yttrium addition can obviously refine the microstructure of magnesium alloy AZ81, reduce the amount of β-Mg17Al12 phase, lead to the precipitation of Al2Y phase and improve the mechanical properties. After solid solution and aging treatment, the tensile strength and elongation of the alloy increase at first and then decrease with the increase of yttrium content, and reach the maxima at 2%Y. At room temperature, the maxima are 277MPa and 10.9% respectively. At 150 , the maxima are 220MPa and 12.4% respectively.

Thermal Simulation Experiment

The effects of deformation temperature on microstructure and mechanical properties of AZ80 magnesium alloy were investigated. The mechanical properties and microstructure were carried out in Gleeble-1500 thermal simulation experiment and optical microscope. The extrusion deformation, dynamic recrystallization had taken place in all the deformation samples, grains were thinner than before deformation.The reasonable deformation process can make the dynamic recrystallization organization of grain smaller and obtain higher strength. The best deformation temperature was about 360°C to 390 °C.
