中文摘要：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。
英文摘要：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.
