摘      要：Lightweight,high-modulus structural materials are highly desired in many applications like aerospace,automobile and biomedical *** the lightest metallic structural material,magnesium(Mg)has great potential but is limited by its low intrinsic Young’s *** paper reviews the investigations on high-modulus Mg-based materials during the last *** nature of elastic modulus is introduced,and typical high-modulus Mg alloys and Mg matrix composites are ***,Mg alloys enhance Young’s modulus of pure Mg mainly by introducing suitable alloying elements to promote the precipitation of high-modulus second phases in the alloy ***,Mg matrix composites improve Young’s modulus by incorporating high-modulus particles,whiskers and fibers into the Mg *** modulus strengthening effectiveness brought by the two approaches is compared,and Mg matrix composites stand out as a more promising *** addition,two well-accepted modulus prediction models(Halpin-Tsai and Rule of mixtures(ROM))for different Mg matrix composites are *** effects of reinforcement type,size,volume fraction and interfacial bonding condition on the modulus of Mg matrix composites are ***,the existing challenges and development trends of high-modulus Mg-based materials are proposed and prospected.
