摘要
以Ti、Al、活性碳粉为组分,采用热压工艺原位合成Ti-Al/TiC金属陶瓷,借助XRD和SEM观察该金属陶瓷的相成分和显微组织。结果表明:在1300～1350℃,原位生成了TiC强化相;将温度升高到1400℃后,TiC与Ti-Al反应生成了Ti-Al-C系三元增强相。
Using the powder mixture of TiAl and active carbon,TiC/Ti-Al cermet was synthesized by hot pressing.The phase content and microstructure of the cermet was investigated by XRD and SEM.The results show that TiC phase can be in-situ synthesized at 1300 ℃～1350 ℃.As the temperature increasing to 1400 ℃,Ti-Al-C ternary reinforcement phase generates in the reaction between TiC and Ti-Al.
