Abstract
The results of studying the effect of Cu and Mg equiatomic content on the diffusion character of atoms in the crystal lattice of a-solid solution at 20°C and the ageing processes of Al−Cu−Mg high-temperature weldable structural alloy are given in the paper. The positive effect of 1151 alloy modification specificity and diffusion processes on the technological efficiency of the structure production processes and the product reliability improvement is also marked. The group of new types of alloys, in particular, Al−Cu−Mg system is proposed to designate as «alloys of equiatomic type» (AET).
