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 AlMgB14 phase is observed in the materials manufactured from a powder mixture subjected to a 4-hour mechanical treatment and sintered at the temperature 1130 degrees C.
