Microstructure and mechanical properties of an Al–TiC metal matrix composite obtained by reactive synthesis

Abstract : "Microstructure and mechanical properties of an Al-TiC metal matrix composite obtained by reactive synthesis", Composites: Part A (2015), 72, 50-57." Abstract: A metal matrix composite has been obtained by a novel synthesis route, reacting Al 3 Ti and graphite at 1000°C for about 1 min after ball-milling and compaction. The resulting composite is made of an aluminium matrix reinforced by nanometer sized TiC particles (average diameter 70 nm). The average TiC/Al ratio is 34.6 wt.% (22.3 vol.%). The microstructure consists of an intimate mixture of two domains, an unreinforced domain made of the Al solid solution with a low TiC reinforcement content, and a reinforced domain. This composite exhibits uncommon mechanical properties with regard to previous micrometer sized Al-TiC composites and to its high reinforcement volume fraction, with a Young's modulus of ~110 GPa, an ultimate tensile strength of about 500 MPa and a maximum elongation of 6%.
