Abstract:

The microstructure, phase composition, and mechanical characteristics of the structural constituents of an Al-Cu-Mg-Si alloy in which the liquation of grain boundaries occurred during heat treatment have been studied. Bands of the (Al + Al-15(Fe, Mn)(3)Si-2) eutectics have been observed at the grain boundaries. An algorithm for calculating the additional pressure, which results from mechanical impact on the metal containing these bands has been described.
