| 摘 要： | 在金属结合剂超硬材料工具的制备中，要求烧结温度尽量低而性能满足对超硬磨粒的支撑、同步磨损和把持。利用机械合金化过程产生的颗粒细化、晶粒细化、表面活化及储能作用可以达到上述要求。通过对机械合金化过程中Cu-Fe系金属粉体的晶粒、缺陷以及局部固溶等现象的分析，认为机械合金化对降低Cu-Fe基超硬材料工具的实际烧结温度和提高综合性能起重要作用。

| Abstract: | It required the sinter temperature as low as possible, but the properties settled for support to the super hard grinding granule, synchronous wear and cling in production of metal agent diamond tools. The above requirement can be attained by the refinement of the granule and the crystalline grain, surface activation and store- energy effect obtained during the process of mechanical alloying. In this paper, the grain, defects and solid solution in local region of Cu-Fe metallic powder reported by other references were analyzed. It is predicted that mechanical alloying will be of great availability for the reduction of the sinter temperature and the improvement of the general properties of the Cu-Fe base super hard material tools. |
