Study on Preparation and High Temperature Mechanical Properties of Mg-3.5Li-6Al Alloy AITranslate
Abstract AITranslate
Mg-3.5 Li-6 Al alloy was prepared by alloy smelting,heating and melting of high-purity raw materials,and flux-mixed gas combined protection.The composition,phase,microstructure and mechanical properties at room temperature or high temperature were tested and analyzed.The experimental results show that the magnesium-lithium-aluminium alloy prepared in this way has uniform microstructure and mechanical properties,mainly composed ofα-Mg and Al-Li phases,and Al-Li is distributed in flakes.The peak value of flow stress increases with the increase of strain rate,and decreases with the increase of temperature.The high temperature deformation constitutive equation of Mg-3.5 Li-6 Al can be described by hyperbolic sinusoidal function.The strain activation energy of the alloy at high temperature is 126 kJ/mol,the stress index is 3.98,and the deformation of the alloy is controlled by intracrystalline diffusion.
