“…Up to now, AlMgB 14 in bulk or powder form has been prepared by several methods like mechanical alloying, hot pressing and pulsed electric current sintering [7,12]. Although most efforts have been focused on preparing AlMgB 14 in bulk or powder form, a few reports have shown preparation as thin films [2,4,[13][14][15][16][17], primarily using pulsed laser deposition (PLD). Limited attempts on preparation by magnetron sputtering have been done.…”

AlMgB 14 coatings have been deposited by DC magnetron sputtering from elemental targets on Si (001), Al 2 O 3 (0001) and MgO (001) substrates at temperatures in the range of 25-350 °C. The structural and mechanical properties of AlMgB 14 films were characterized by X-ray diffraction, scanning electron microscopy, nanoindentation, and analyzed as a function of deposition conditions and substrate materials. The results show that all films are X-ray amorphous, and the mechanical properties of the deposited films depend on the substrate and growth temperature. AlMgB 14 thin films deposited at 350 °C are found to have smoother surfaces and containing more well-formed B 12 icosahedra than the films deposited at lower temperature, which consequently increase the hardness of the deposited films. The maximum hardness and Young's modulus of the as-deposited films are about 32.3 GPa and 310 GPa, respectively, for films deposited on Al 2 O 3 substrate at 350 °C.

“…As a new engineering ceramic, the environmental stability is an important criterion for its actual applications, since the material will be inevitably exposed to high temperatures. There have been several reports [9][10][11][12] on the synthesis and mechanical performance of AlMgB 14 -TiB 2 ceramic.…”

The isothermal oxidation behavior of AlMgB 14-TiB 2 composite was investigated at the temperature range from 600 °C to 1000 °C in air for 10 hours. The results showed that the oxidation kinetics of this composite obeyed the parabolic law with an activation energy of 176 ± 20 KJ•mol-1 from 700 °C to 1000 °C, the corresponding parabolic rate constant increased from 0.0069×10-8 kg 2 •m-4 •s-1 to 138.75×10-8 kg 2 •m-4 •s-1. The SEM micrograph of the oxidized surface at 700 °C for 10 h indicated that only the TiB 2 phase was changed. The AlMgB 14 phase changed at 800 °C in air, and the oxide scale consisting of TiO 2 and borate glass dissolved with MgO and Al 2 O 3. Meanwhile, a number of pores also existed in the oxide scales. The oxide scales at 1000 °C were divided into three layers: an outer glassy B 2 O 3 layer, a middle oxide layer with small size pores, and a reaction layer with large size pores formed as the oxidation of the AlMgB 14 phase. The formation mechanism of the oxidized layers was analyzed.

“…The hardness of AlMgB 14 can be enhanced by adding an additive, such as TiB 2 [5]. Li [6] used two steps to sinter the AlMgB 14 -TiB 2 . Firstly the AlMgB 14 -xTiB 2 was sintered by uniformly mixing B, Mg, Al powders and different contents of Ti powders, and then the samples were sintered at a temperature of 1050 1C in a vacuum to form AlMgB 14 -TiB 2 .…”
