Abstract

Homogenizing annealing of ingots is held to dissolve the nonequilibrium excess phases, eliminating intergranular segregation and reduce internal stresses in the ingots of aluminum alloys. Simultaneously, there is a process of disintegration of solid solution of aluminum small additions of transition metals( manganese, chromium, zirconium) to form dispersoids. The influence of different modes of homogenization on the volume fraction of nonequilibrium structural components, the properties of the 1933 alloy ingot at elevated temperatures, density of distribution and size of Al3Zr dispersoid are represented.
