The first one consists on milling Al powder in an ammonia gas atmosphere. In the second method, the Al powder is milled in vacuum with the addition of solid urea. In both cases, the milled powders are consolidated to full density by a conventional press-and-sinter powder metallurgy (PM) technique. The produced composites consist on a nanostructured aluminium matrix reinforced with self-forming nanocrystalline nitrides dispersoids. Consolidated compacts reach full densification, and show a high tensile strength (up to 550 MPa) and an outstanding high-temperature behaviour. |
