Studies of the relationship between the microstructure and anisotropy of the plastic properties of industrial aluminum-lithium alloys

Al-Li alloys are one of the groups of materials used in the modern aircraft industry. Their mechanical properties make them very attractive for this application. A considerable plastic deformation during the technological operation results in the development of a significant crystallographic texture in the Al-Li alloys. In this paper we show the results of studies on the anisotropy of the properties of the 8090 alloy with attention paid to precipitates and the anisotropy of all the pertinent elements in the materials microstructure.
