Synthesis of AlMgB14: Influence of Mechanical Activation of Al–Mg–B Powder Mixture on Phase Composition of Sintered Materials

An investigation of the size distribution and phase composition as well an analysis of the Al–Mg–B powder system are performed as a function of the time of mechanical activation in a planetary mill and heat treatment regimes. It is found out that the largest content of the AlMgB 14 phase is observed in the materials manufactured from a powder mixture subjected to a 4-hour mechanical treatment and sintered at the temperature 1130°С.
