Abstract

Effects of high pressure treatment on microstructures and mechanical properties of AM60 B magnesium alloy were investigated by X-ray diffraction

optical microscopy and scanning electron microscopy.The results show that with pressure

the grain size of AM60 B magnesium alloys is refined with uniform distribution.High pressure aging treatment can affect the morphology and distribution ofβ-Mg

phase.With the 2GPa pressure of aging treatment

the compression strength is increased by9% compared with that of aging treatment ones under ambient pressure.
