“…Doping and solid-solution have been introduced to further improve the mechanical, electrical, thermal and oxidation resistant properties of these two materials [36][37][38][39][40]. MoAlB and Fe 2 AlB 2 have also served as precursors for two-dimensional MBene with excellent electrical, magnetic and electrocatalytic performance [41][42][43] and reinforcement component in composite materials to increase the wear and oxidation resistance [44][45][46][47].…”

Similar to Mn+1AXn (MAX, M: transition metal, A: A group element, X: C or N, n=1~3) phase materials, MAB (M: transition metal, A: A group element, B: B) phases also exhibit excellent comprehensive mechanical and thermal properties that are applicable to future nuclear reactors. The origination and growth conditions of He bubbles under irradiation in MAB phase MoAlB and Fe2AlB2 have been calculated through first-principles theory in this work. In general, Fe2AlB2 may present lower single/double vacancy formation energies and a consequent higher He bubble number density. The final He bubble shape and comparative average size of MoAlB and Fe2AlB2 have been predicted as well. In MoAlB there will form large platelet-like He bubbles and small spherical ones. In Fe2AlB2 there will form spherical He bubbles with different sizes. These He bubbles can all further link via interlayer vacancies into string-like shape. Fe2AlB2 also possesses higher He-induced embrittlement tendency than MoAlB.

The microstructure, mechanical properties, and phase stability of TiN+MWCNTs ceramic-based composite were studied. Ball milling and spark plasma sintering (SPS) techniques were adopted for synthesizing titanium nitride (TiN) composites containing 1, 3, and 5 wt. percent (wt. %) multiwalled carbon nanotubes (MWCNT). At a temperature of 1000 °C where the phase stability was investigated, the effects of MWCNT addition on thermal treatment and mechanical characteristics of the fabricated composites were explored. According to the results, the resultant effect of ball milling on the ad-milled powders and sintering at a temperature of 1800 °C played a critical role in the homogenous diffusion of MWCNTs into the TiN ceramic matrix. It was further noted that the addition of different wt. % of multiwalled carbon nanotube helped in stabilizing the FCC-crystal phases at this elevated temperature. A slight transformation was observed in the microstructures, as the core and the outer rim phases remained stable in their crystallographic orientation. The varying addition of MWCNTs retained the α-FCC phase both at the core and the outer rim phase during and after thermal exposure of 1000 °C for 3 h. The composite with 1wt. % MWCNT content exhibited the highest hardness of 40 GPa with a fracture toughness of 12.22 MPa m1/2, while the least hardness value of 12.5 GPa was recorded by the unreinforced TiN sample. The effect of mechanical alloying and thermal exposure of the ceramic composites significantly enhanced the strengthening and toughening of the composites.
