In work studies of materials obtained from various powder mixtures Al-Mg-B after mechanical processing in a planetary mill and subsequent vacuum sintering were carry out. It was found that for each mixture exists optimal time of mechanical treatment in a planetary mill, at which the maximum content of AlMgB14-phase is reached. It was shown that for the samples synthesized from the Al-Mg-B powder mixture with the dispersion of the raw aluminium powder <d>~80 μm after 5 hours of mechanical activation and subsequent vacuum sintering at a temperature of 1130 °C, the maximum phase of AlMgB14 is ~ 85-90 wt.%.
