Structure and nanomechanical characteristics of Al–Cu–Mg–Si alloy with partly liquated grain boundaries upon heat treatment

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 gra...

Zusammenfassung: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.
