摘　　要：综述了粉末冶金温压工艺的研究进展,概述了温压工艺的粉末原料、聚合物、温度、压力、烧结环节对温压工艺的影响和温压工艺的致密化机理。详细介绍了温压工艺的新进展—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 P/M parts at low cost. This paper reviews and discusses the effects of the powder materials, polymer, temperature, compressive stress, sintering on warm compaction and the densification mechanism of the warm compaction. The development of warm compaction-warm flow compaction, high compacting pressure warm compaction are introdued, and the potential application of warm compaction is presented in the paper.
