摘　　要： 主要介绍了温压技术的研究概况,对其关键技术(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全面的综述.粉末冶金温压技术绝大部分受到国外严格的专利保护,因而研究开发出拥有自主知识产权的温压技术,具有重要的现实意义。并指明在不久的将来,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,温压粉末冶金零件的潜在市场十分广阔。 This paper gives a briefing on the research progress in warm compaction technology. Densification mechanism, warm compact materials, numerical modeling, industrial applications, and the key techniques in warm compaction such as powders, Iubricants, warm compaction temperature and warm compaction system are overviewed. The paper points out that the history of warm compaction research and development in China is only a few years old and most of the warm compaction techniques are protected by foreign patents, therefore, to develop our own patents of warm compaction technique 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 widen, the potential markets in the warm compacted powder metallurgy parts are very attractive.
