随着航空工业的飞跃发展,对轻合金材料的比重及综合性能提出了越来越高的要求。现有牌号的镁合金是现代工业用合金中比重最轻的一种合金,进一步减轻镁基合金的比重,对于航空工业具有十分重要的意义。以镁—锂为基的超轻镁合金,是近年来世界各国广泛研究的一种新合金。特别是当锂含量大于10%时,镁—锂合金的结构发生了质的变化。由密排六方晶格的α相
With the rapid development of aviation industry, the proportion of light alloy materials and overall performance put forward higher and higher requirements. The current grade of magnesium alloy is the lightest alloy in modern industrial alloys, and further reducing the proportion of magnesium-based alloy is of great significance to the aviation industry. Magnesium - lithium-based ultra-light magnesium alloy, is widely studied in recent years in all countries in the world a new alloy. In particular, when the lithium content is more than 10%, the structure of the magnesium-lithium alloy undergoes a qualitative change. By dense hexagonal lattice α phase
