摘　　要：分析了铁粉、铜粉在冷等静压下材料的致密化过程。常用的Ｆｌｅｃｋ和Ｓｈｉｍａ模型得到了应用和讨论。与实验数据对比可知：不考虑基体材料塑性硬化的Ｆｌｅｃｋ模型可较好地模拟金属粉末在冷等静压下的致密化过程。Densification behaviours of copper and iron powders nuder CIP were analyzed. Fleck model and Shima model which are often used were discussed. As compared with experimental data, it can be concluded that Fleck model without plastic hardening could simulate well the densification behaviours of metal powders under CIP process.
