What is AlMgB14 ceramics were reported as high-hardness materials over a decade agomagnesium boride

AlMgB14 ceramics were reported as high-hardness materials over a decade ago. While different synthesis routes for processing AlMgB14 ceramics were reported in the past, the synthesis routes are still not optimized and present a significant challenge to the manufacturers. This work explored six different synthesis routes for the synthesis of AlMgB14 powder. The synthesized compositions were characterized by XRD, where weight fractions of each phase were calculated by Rietveld refinement. Hardness and indentation fracture resistance of AlMgB14 ceramics were measured to be 26.7 ± 2.2 GPa and 5.59 ± 0.42 MPa m1/2, respectively, by the Vickers indentation technique. Under an oxygen atmosphere, thermogravimetry–differential scanning calorimetry showed that the heat release of the prepared material was much higher than that of untreated boron. Arkhipov et al. investigated the ignition and combustion of mixed powder composed of aluminum, boron, and boron–aluminum alloy powder with an adhesive and oxidizing agent (ammonium perchlorate/ammonium nitrate). The results showed an increased combustion rate of the mixed powder containing the boron–aluminum alloy powder. Wainwright et al. prepared Al: Zr, Al-8Mg: Zr, and Al-38Mg: Zr nanocomposite particles by physical vapor deposition (PVD) and ball-milling. The SEM results showed significant particle sintering for both PVD and ball-milled particles and all three compositions. AlMgB14 ceramics were reported as high-hardness materials over a decade ago.
