AlMgB14 is of great interest due to its extreme hardness, low density, high thermal stability and desirable thermoelectric properties. AlMgB14 is a very promising candidate as wear-resistant, self-lubricating and protective coatings for cutting tools and protective coatings for micro devices and micro electromechanical components. Some methods for preparing AlMgB14 super-hard materials were introduced, especially a two-step heat treatment method. AlMgB14 disks were synthesized at ambient pressure through a two-step heat treatment. In the first step, MgB2 disks doped with Al and Ti were fabricated through composition of uniformly mixed Mg, B, Al powders and different contents Ti powder in the form of pressed disks heated at 850 ℃ for 2 hours in closed argon atmosphere. And in the second step, target AlMgB14-TiB2 disks were obtained after sintering the MgB2 disks at 1050 ℃ for 0.5 hours in vacuum. The phase, microstructure and superconductivity were characterized by means of X-ray diffraction (XRD), Scanning electron microscope (SEM) and superconducting quantum interference device (SQUID). The grain size of AlMgB14 is fine and the nano-scale TiB2 particles as the second phase induced by Ti doping are uniformly distributed in the sample matrix. The research status on bulk and film of AlMgB14 and the future researching scope of AlMgB14 were introduced.
