Synthesis of AlMgB14: Effect of modes of mechanical activation of the raw powders on the properties of obtained materials
National Research Tomsk State University, Tomsk, 634050, Russia
In work studies of phase composition, hardness and density of materials based on AlMgB14 synthesized by hot pressing method at temperatures of 1300 and 1400 °C under pressure 50 MPa from aluminum, magnesium and boron powders (E1 mixture), as well as from original powder of aluminum-magnesium alloy (E2 mixture) were conducted. AlMgB14 phase content of obtained bulk samples is ~ 95 wt. %. The maximum hardness of 14GPa and density of 2.1 g/cm3, respectively, has a sample, marked as E1, synthesized at a temperature of 1400 °C.
