Abstract
Boron nitride nanotube (BNNT)-magnesium (Mg) alloy composites and methods of fabricating the same are provided. The BNNT-Mg alloy composites can have a sandwich structure and can be fabricated by high-pressure spark plasma sintering. A mat of BNNTs can be sputter-coated with Mg, and then sandwiched between Mg alloy particles, followed by a sintering step. The BNNTs can include a hexagonal boron nitride phase.
