摘　　要：温压是一项以较低的成本制造高性能粉末冶金零件的新型成形技术,本文综述并讨论了温压工艺的粉末原料、聚合物、温度、压力、烧结环节及致密化机理。在此基础上,介绍了温压工艺的新发展———流动温压、高压温压等,并对其应用前景进行了展望。Warm compaction is a new forming technique for fabricating high performance ferrous PM parts at low cost. This paper reviewed and discussed the powder materials, polymer, temperature, compressive stress, sintering and its densification mechanism of the warm compaction. The new development of warm compaction-warm flow compaction, high compacting pressure warm compaction etc., and the potential application of warm compaction was presented.
