| 摘 要： | 在真空条件下采用高能球磨法以不锈钢粉末、钛粉和碳粉为原料制备了不锈钢-TiC超细复合粉末.X射线、扫描电子显微镜、比表面积评价等分析技术被用来对球磨过程中粉末的微观状态进行了分析.结果表明,随着球磨时间的增加,不锈钢复合粉末逐渐细化,用X射线衍射方法计算的最终晶粒可达到20nm.同时,钛粉和碳粉在球磨过程中发生反应形成TiC,可获得纳米级的不锈钢-TiC复合粉末.

| Abstract: | High-energy ball mill method was used to fabricate the stainless steel nanocomposite powder from stainless steel powder, carbon powder and titanium powder as raw materials. The X-ray diffraction, SEM and the BET method were used to evaluate the microstructure of treated samples. The results showed that in vacuum condition,with ball mill time increase, stainless steel powder become more and finer, the grain size can reach nanometer level. At the same time, the nano TiC can be formed during ball milling, the stainless steel-TiC nano composite powder can be obtained. |
