Abstract

The phase composition of aluminum Al–B–Cu–Mg alloys has been studied using calculations and experimental methods. Unlike copper, magnesium is shown to substitute aluminum in the AlB2 phase substantially. The use of Al–Cu–Mg alloys (duraluminums) as the matrix of boron/aluminum composite prepared by liquid-phase technologies is substantiated.
