摘 要: 分析了金属粉末模压下的致密化过程。将岩石力学中的Cam-Clay模型用于该过程的分析，并与常用的Fleck和Shima模型进行比较。经实验验证得知：Cam-Clay模型能够较精确地分析金属粉末的模压致密化过程，而Felck和Shima模型的分析误差较大。

Abstract:Die compaction densification behavior of metal powders was analyzed. Cam-Clay model in rock mechanics was introduced, and compared with often-used Shima model and Fleck model. From experimental comparison, it revealed that Cam-Clay model can simulate well die compaction densification behavior of metal powders, while Shima model and Fleck model can't.
Key words: metal powder; die compaction; densification behavior; Cam-Clay model
