预烧温度对纳米复合Ti(C,N)基金属陶瓷组织和性能的影响
The Influence of Pre-sintering Temperature on the Microstructure and Properties of Nano-composite Ti(C,N)-based Cermets
摘 要
用真空预烧＋热等静压处理工艺制备了纳米复合Ti(C,N)基金属陶瓷,用SEM和TEM/EDX研究了预烧温度对纳米复合Ti(C,N)基金属陶瓷显微组织和性能的影响.结果表明：随着预烧温度的升高,硬质相颗粒明显球化、细化且分布均匀,具有白芯-灰壳结构的小硬质相颗粒明显增多,且环形相较完整.在1 420 ℃预烧时,金属陶瓷具有较好的力学性能;继续升高预烧温度时,晶粒会明显长大,环形相变厚、变脆,导致材料的性能下降.综合考虑认为,较佳预烧结温度为1 420 ℃.

Abstract
The nano-composite Ti(C,N)-based cermets were produced by vacuum pre-sintering and post-hot isostatic pressing technology.The influence of pre-sintering temperature on the microstructure and properties of nano-composite Ti(C,N)-based cermets has been studied using SEM,TEM and EDX.With the increase of pre-sintering temperature,the grains were spheroidized gradually and distributed evenly,the size of grains decreased,the small grains with inner-rim and outer-rim and white core-gray hull increased greatly and the rim phase was complete.For the nano-composite cermets sintered at 1 420 ℃,it could acquire satisfied microstructure and good properties.When the pre-sintering temperature increased further,the crystalline began to grow,the rim phase became wider and the properties of cermets decreased.The optimal pre-sintering temperature of nano-composite Ti(C,N)-based cermets was 1 420 ℃.
