摘　　要：以电解铜粉和雾化铜粉为SPS烧结原材料,对它们在SPS烧结过程中的烧结曲线、烧结体显微组织的演变过程,以及烧结温度对烧结体相对密度的影响进行了分析、比较,并分析了其中的原因。得到电解铜粉和雾化铜粉在SPS烧结过程中显微组织演变特征和规律不同的结论。In the paper, electrolytic copper powder and atomizing copper powder was used, the differences of sintering curve during SPS process and the microstructure evolution in different sintering stages, the relative density in different sintering temperature are studied, and the reason was analysis. We get the conclusion that the microstructure evolution of electrolytic copper powder and atomizing copper powder was different in SPS process.
