Status and prospects for aluminium-lithium alloys in aircraft structures

摘要: Abstract This paper examines the status and prospects for widespread application of AlLi alloys in aircraft structures. Particular attention is paid to damage tolerance engineering properties fatigue crack growth fracture. At present very limited. because they are not direct replacements conventional basic material costs usually too high. Widespread may well require a new generation alloys, especially primary will take at least five years. In meantime, experience be gained by selective current secondary
