Abstract

An increase of weight efficiency of perspective aerospace vehicles is possible by using aluminium-lithium alloys with low density. Perspective, hi-strength, hi-stiffness, alloy V-1469, based on Al Cu Li system and alloyed with Ag, Sc and Zr, has been developed in VIAM. Industrial technology of manufacturing extruded products from V-1469 alloy was developed. Pressing temperature was chosen. Effects of heat treatment on structure and mechanical properties were studied. Complex of mechanical, corrosion and resource characteristics was investigated.
