Abstract:

Particles reinforced Mg Li matrix composites, as an emerging super light structural metallic material, have been expected to be widely used in aerospace and civil fields, such as transportation, electronics packaging and sports industry for their high specific strength and specific stiffness, good damping and electromagnetic shielding properties. Firstly, the research status of ultrafine intermetallic compound particles reinforced Mg�睱i matrix composites including applications, microstructures, mechanical properties and processing technologies were summarily related. Secondly, the progress 〖JP〗in the research of ultrafine intermetallic compound particles reinforced Mg�睱i matrix 〖JP+1〗composites were expounded. Especially for the simulation model incorporating transition interface layer and strengthening mechanism, their test verification in  ultrafine compound particles reiforced Mg�睱i matrix composites were emphatically introduced. Finally, the prospects on the research direction and development tendency of ultrafine intermetallic compound particles reinforced Mg�睱i matrix composites were expected based on the opportunities and problems in future.
