Abstract Scope |
The engineering application of ultra-light Mg-Li alloys is seriously restricted because of their low strength, poor stability and high temperature performance. Ultralight Mg-Li-X alloys with high strength were designed and prepared via the introduction of alloying element and plastic deformation. Ultralight Mg-Li-Al-Sn, Mg-Li-Al-Mn and Mg-Li-Al-Ca alloys with high strength and good damping capacities have been developed in our research group. The microstructure, mechanical properties and damping property of Mg-Li-Al-X alloys were investigated systematically combing the usage of many advanced microstructure characterization methods and normal tensile tests, etc. The results from this research provide important technological support for the controlling of microstructure, mechanical properties and damping capacities of Mg-Li alloys. |
