摘　　要：主要介绍了温压技术研究概况 ,对其关键技术 (包括粉末、润滑剂、温压温度和温压系统 )、致密化机理、温压材料、数值模拟及其工业化应用的最新研究进展进行了较全面的综述 .目前 ,国外粉末冶金温压技术绝大部分受到专利保护 ,国内研究时间较短 .因而 ,研究开发出我国拥有自主知识产权的温压技术 ,具有重要的现实意义 .在不久的将来 ,高性能铁基粉末冶金零件在汽车、机械工业中的应用将不断扩大 。This paper gives a briefing on the research progress in warm compaction technology. Densification mechanism, warm compaction materials, numerical modeling, industrial applications and the key techniques in warm compaction such as powders, lubricants, warm compaction temperature and warm compaction system are reviewed. The paper points out that the history of warm compaction research and development in China is only a few years old and that most of the warm compaction techniques are protected by foreign patents. Therefore, to develop our own patented warm compaction techniques is important for our powder metallurgy industry. In the near future, applications of high performance iron_base powder metallurgy parts in automobile and mechanical industries will be widened and the potential market for the warm compacted powder metallurgy parts are very attractive.
