外文摘要：Magnesium alloys are the lightest metal structural materials owing to their excellent physical and chem-ical properties.Microstructural evolution in magnesium alloys under the conditions of casting,thermal-mechanical processing,and in-service environment,play an important role in governing their mechanical properties and reliability/sustainability.A synchrotron light source produces high flux,tunable X-ray en-ergy,high resolution,and high coherence X-ray beams,which can realize in-situ dynamic observation of microstructural evolution in a wide range of alloys during the entire processing chain and in simulated service environments.This article reviews the fundamentals of synchrotron radiation characterization techniques(imaging,diffraction,scattering,and fluorescence holography)and state-of-the-art advanced synchrotron characterization techniques on the microstructure evolution mechanism of magnesium al-loys.Case studies span a broad range of solidification,deformation,precipitation,fracture and damage,corrosion,and energy storage.Research opportunities and challenges of physical metallurgy studies of magnesium alloys are highlighted for future studies.
