摘要
综合论述了工业Al-Li合金的发展,Al-Li合金的相变、组织,Al-Li合金的强化机制,Al-Li合金的塑件、韧性问题,热处理及机械性能。指出,研究热处理(特别是形变热处理及分级时效)、合金化及微合金化对Al-Li合金组织、性能的影响是改善Al-Li 合金短横向性能,并进一步提高合金的塑性、韧性及耐蚀性的主要途径。
The development of industrial Al-Li alloy and their phase transformation,structure,hardening mechanism,ductility and toughness were reviewed.The research on theeffects of thermomechanical treatment,step-aging,alloying and microalloying on the structureanol properties of Al-Li alloy,it is found the wain route for improving the properties,especiallythe short transverse mechanical and corrosion resistance properties of Al-Li alloys.
