Effect of Autoclave Processing Parameters Used to Form Hybrid SIAL Parts on the Structure and Properties of Al–Li Alloy 1441 Sheets
摘要
Abstract
The main stages of developing hybrid SIAL-type composite materials based on alloy 1441 sheets are considered. The technological process of manufacturing aviation products from them by autoclave forming includes additional heating of heat-treated alloy 1441 sheets, which are part of the structure of a hybrid material. The changes revealed in the aluminum–lithium alloy sheets during studying of their microstructure, the number of precipitated phases, and their mechanical properties are shown to weakly affect the hybrid SIAL composite material.
