Microstructure of AM60 magnesium alloy by high-pressure solution and subsequent atmospheric-pressure aging treatment
As-cast AM60 magnesium alloy was solid dissolved with exercising different pressures (atmospheric-pressure,3,4 and 5 Gpa) to it and subsequently aged under atmospheric pressure.The microstructure of the products was characterized by optical microscope and X-ray diffraction.The results show that,compared with exercising atmospheric-pressure during solution treatment,exercising high-pressure during this process causes that the α-Mg grains of the subsequent aging alloy are more fine and uniform,while the β-Mg17Al12 phases transform into fine particles and aggregate to form gobbets or strips.In addition,increasing the exercising pressure promotes the precipitation of the β-Mg17Al12 phases of the aging alloy.
