有下一代飞机用材之称的铝锂钪合金在俄罗斯得到迅速发展。首先在铝锂合金中加钪合金化的是１４２１和１４６０。其强度与焊接性能远高于１４２０及１４５０合金。近年在铝锂合金中加钪又加锆的有１４２３、１４２４为铝锂镁合金，用作焊接和铆接结构，其重量轻、抗蚀性高，冶?
The next generation of aircraft materials known as aluminum lithium scandium alloy in Russia has been rapid development. First in the aluminum-lithium alloy plus scandium alloying 1421 and 1460. Its strength and weldability are much higher than 1420 and 1450 alloys. In recent years in the aluminum-lithium alloy plus scandium plus zirconium 1423,1424 for the aluminum lithium-magnesium alloy, used for welding and riveting structure, its light weight, high corrosion resistance, metallurgical?
