摘要
采用Gleeble热模拟机对75Fe-25(Ti+C)体系在电场作用下的燃烧合成进行探讨,结果表明:这种不能采用普通SHS技术进行燃烧合成的体系,当预设升温速度为600℃/s时,在电场作用下仍不能实现燃烧合成;而当预设升温速度提高到1 000℃/s时,在电场作用下该体系能在743℃发生燃烧合成反应,合成产物由TiC和Fe组成,其中细小的TiC颗粒有一定程度的团聚现象。
Using Gleeble thermal simulation equipment, the combustion synthesis of 75Fe-25 （Ti＋C） system under the action of electric field was studied. The results show that this system, which can＇t be synthesized by conventional SHS, can＇t yet achieve the combustion synthesis at preset heating rate 600℃/s even under the action of electric field. However, when the preset heating rate rises up to 1000℃/s, the combustion synthesis can take place at 743℃ in this system. Moreover, the synthesized products consist of TiC and Fe, and the fine TiC particles reunite to some degree.
