摘　　要：在利用粉末冶金工艺制备铁基混合粉末过程中,由于铁基零部件各组分的密度及粒度差异,混合料经常存在偏析现象,这会引起烧结产品尺寸和性能的不稳定,因此对混合料的成分偏析程度进行测试或评定具有实际意义。本文系统总结了铁基混合料成分偏析分析方法,包括耐扬尘性分析法、成分分析法、色泽观察法、烧损测试法;在实际工程中,可以根据实际需求选取上述试验方法。Due to the differences in density and particle size of raw material segregation of iron-based mixed powders is outstanding, leading to the instability components during manufacturing process, the in product size and properties. Therefore, it is necessary to estimate the component segregation degree of mixture. The test methods of component segregation for iron-based mixed powders were systematically summarized in this paper, including dust test, component analysis, colour observation, and sintering loss rate, the suitable methods could be selected according to engineering application.
