摘要：

Aluminum metal matrix composites (MMC) dispersed with particulate titanium nitride were prepared by ball milling of elemental powders Al and Ti with ring-type organic compound pyrazine in benzene solution. A one-step formation process could not form the desired Al-TiN MMC. The composite was obtainable only by a subsequent thermal treatment. For two-step processing, the TiN formed in the early stage of milling could then be dispersed in the Al matrix homogeneously and Al-TiN composite could be successfully synthesized. The crystalline size of TiN was found to be 9 nm. © 2000 Acta Metallurgica Inc.
