Abstract

Explosive shock-compression processing is used to fabricate Ti3Al and TiAl composites reinforced with TiB2. The reinforcement ceramic phase is either added as TiB2 particulates or as an elemental mixture of Ti + B or both TiB2 + Ti + B. In the case of fine TiB2 particulates added to TiAl and Ti3Al powders, the shock energy is localized at the fine particles, which undergo extensive plastic deformation thereby assisting in bonding the coarse aluminide powders. With the addition of elemental titanium and boron powder mixtures, the passage of the shock wave triggers an exothermic combustion reaction between titanium and boron. The resulting ceramic-based reaction product provides a chemically compatible binder phase, and the heat generated assists in the consolidation process. In these composites the reinforcement phase has a microhardness value significantly greater than that of the intermetallic matrix. Furthermore, no obvious interface reaction is observed between the intermetallic matrix and the ceramic reinforcement.
