TiC纳米晶粉的制备及特性

PREPARATION AND CHARACTERISTICSOF NANO TiC MICRO POWDER

采用机械合金化方法制备了ＴｉＣ纳米晶粉末，研究了这种纳米晶粉末的微观结构和性能。结果表明：机械合金化处理５０ｈ，可以获得平均粒径为３０ｎｍ的ＴｉＣ纳来晶粉。

Nano TiC micropowder is prepared by mechanical alloying.The authors study its microstructure and performance.The results obtained indicate that 30 nm TiC micropowder can be obtaied by mechanical alloying for 50 h and its microhardness increases considerably with ball milling time.
