| Abstract Scope |
Titanium matrix composites (TMCs) reinforced with ceramic particles combine the high strength and thermal resistance of ceramic with the ductility and toughness of titanium. In this study the LENSTM additive manufacturing system was used to produce TiC reinforced Ti-Ni matrix composites (TNMCs) with varying carbon percentages which are suitable for ballistic and defence applications. While mechanical response of the as-deposited TiC reinforced TNMCs is promising, brittle failure is displayed at higher carbon weight percentages which is undesirable for practical applications. To increase their toughness, additively manufactured TiC reinforced TNMCs were subject to two heat treatments with their influences on microstructure and mechanical properties investigated, its influence on the mechanical properties of the TiC/TNMC will be presented. |
