Effect of exercising pressure during solid solution on microstructure and mechanical properties of AM60 magnesium alloy
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-Mg17A12 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.
