放电等离子烧结ＴｉＢ２过程中真空室气压Ｐａ有二个峰值，本文对Ｐａ第二峰进行了研究．研究结果表明：Ｐａ第二峰是烧结过程中化学反应导致的气相沉积所致．原始粉末和烧结工艺对Ｐａ第二峰有影响，而Ｐａ第二峰也影响烧结材料的微观结构．
There exist two Pa peaks of vacuum pressure when TiB2 is consolidated by Spark Plasma Sintering. The second Pa peak was investigated in this paper. The results indicate that it is caused by vapor deposition from chemical reaction in sintering. The state of original pow- der and sintering technology have influence on the second Pa peak which also has effect on the microstructure of the sintering materials.
