挤压Mg-Li-Zn-RE合金的塑性流变特征研究

前言:
畸of the alloy.Mg—Li aUoys have considerable potentiaI applications in automotive,aerospace and electronic devices due to their low density and high specific strengtho卜j。. However, 印pIications of Mg—Li alloys are stiU limited because of the low stren昏h,poor creep resistance and the咖al stabili饥 due to the ve眄high diffusional mobil耐of Li州. The preVious s订engtbening methods,such as Zn or Al elements alloying and severe p......
