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.
