Abstract
The Cu-based composites are excellent candidates for applications that require a high strength and a good electrical conductivity. Recently, combustion synthesis or self propagating, high-temperature synthesis (SHS) using powder compacts has been developed to produce intermetallics or ceramics. It is also possible to form metal-intermetal li c or metal-ceramic composites from combustion reactions between corresponding elemental constituents. It has the advantage of an in-situ forming technique compared with conventional artificial comosite production approaches.
In the present study, combustion reaction was carried out to form Cu-based composites in the Cu-Ti-BN system. The compacts of Cu and Ti powders with BN powder reacted exothermically, and formed a mixture product which had a fine distribution of the TiB2 and TiN particles in the Cu matrix. The processing technique, therefore, is of interest as a combustion reaction synthesis to make in-situ metal-based composite materials.
