摘　　要：铁粉的压缩性对产品性能有重要影响。概述了影响铁粉压缩性的因素,其粉末自身属性包括杂质元素含量、粉末粒度及配比、颗粒形貌等。探讨了一些新工艺的影响,主要包括等静压技术,高速压制技术,温压技术,超声振动技术等。结果能为提高粉末压缩性提供理论依据。Compressibility of iron powders has an important influence on product properties. Factors affecting the compressibility of iron powder were summarized. The powder properties included impurity elements, particle size and composition, particle morphology, etc. The impact of some new technology was discussed, including isostatic pressing （IP）, high velocity compaction （HVC）, warm compaction （WC）, ultrasonic vibration （UV）, etc. The results can provide theoretical basis for improving powder compressibility.
