Mab Phase-Alumina Composite Formation Via Aluminothermic Exchange Reactions

Materials Letters, 2023
The formation of MAB phase-alumina composites through aluminothermic exchange reactions using M-element (Fe, Mn, Cr, Mo, W) oxides has been investigated for the MAB phases Fe2AlB2, Mn2AlB2, Cr2AlB2, MoAlB, and WAlB for the first time. With the exception of WAlB, all systems formed MAB phase and alumina as major phases, with binary M-element borides ...
