用Al、Zn、Cd、Ag和某些其他元素合金化的含>10%Li的镁合金作为超轻材料(比重为1.30~1.45克/厘米~3是具有很大意义的。在以前发表的文献中,已说明了LA 141和LA 142合金的制成,这两种合金目前推荐用于减轻重量的许多结构。这些合金是含13~15%Li、0.75~20%Al和少量其它添加元素的镁基合金。我们在研究以β-相为基础的(11~16%Li)二元和三元Mg-Li合金的组织和机械性能方面
Magnesium alloys containing> 10% Li alloyed with Al, Zn, Cd, Ag and some other elements are of great interest as lightweight materials (specific gravity of 1.30 to 1.45 g / cm 3) In the literature, the preparation of LA 141 and LA 142 alloys, which are presently recommended for many weight reduction structures, has been described as containing 13-15% Li, 0.75-20% Al and minor amounts of other additional elements Of magnesium based alloys.We investigated the microstructure and mechanical properties of β-phase based (11-16% Li) binary and ternary Mg-Li alloys
