1450Al-Li合金挤压半成品在现代运输机结构中的应用

Application of Extruded Semi-finished Products from 1450 Al-Li Alloy on Structure of Modern Airfreighter

本文研究了化学成分、时效规范、淬火与时效间的变形、织构和晶粒组织对1450合金性能的影响。所得到的规律有助于对具有综合性能的1450合金挤压半成品生产的掌握及保证半成品在飞机上的广泛应用。

The effect of elemental composition,ageing specification,deformation between quench-ing and ageing,texture and crystal structure on performance of 1450 alloy was studied inthis paper.Obtained law can be useful for control of production of extruded semi-finishedproducts with synthetic properties,and ensure of extensive use of semi-finished products onaircraft.
