| 摘 要： | 以不锈钢粉末、钛粉和碳粉为原料，通过高能球磨法在真空条件下制备了不锈钢-TiC超细复合粉末。采用X-ray、扫描电镜、透射电镜、比表面积评价等分析技术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，最终可达到纳米级。同时，钛粉和碳粉在球磨过程中反应形成TiC．并在不锈钢晶内形成TiC纳米粒子。

| Abstract: | Taking stainless steel powder, carbon powder and titanium powder as raw materials, the stainless steel nano-composite powder was prepared by high-energy baU-miUing method. The X-ray diffraction, SEM and the BET method were used to evaluate the microstructure of treated samples. The results show that in vacuum condition, with ball- milling time increasing, 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 particle can be obtained. |
