Project leader:Martin Balog
The project was focused on research of ultra-fine grained Al-AlN metal matrix composites derived from Al powders. Al-AlN composites were prepared via unique technique compromising suitable consolidation of Al-AlN bodies obtained by direct nitridation of fine Al powder precursors. The goal of the project saw to enlighten mechanisms and behaviours linked with formation of AlN layer during nitridation. Deformation behaviour and functional characteristics of final Al-AlN composites were pursued. Obtained results yielded knowledge required for technology optimization at industrial scale.
