Effect of Exercising Pressure during Solid Solution on Microstructure and Mechanical Properties of AM60 Magnesium Alloy

Abstract:

As-cast AM60 magnesium alloy was solid dissolved with exercising different pressures to it. The microstructure of the products was characterized by optical microscope and X-ray diffraction. The mechanical properties of the products were investigated by microhardness tester and tensile testing. The results show that increasing the exercising pressure promotes the fracture and dissolution into the α-Mg matrix of the coarse β-Mg₁₇Al₁₂ phases distributed along the grain boundaries with a network appearance. With increasing the exercising pressure, the tensile strength, elongation percentage and percentage reduction of area of the alloy significantly increase, but its microhardness decreases.
