研究了Al6061铝合金粉末在冷压条件下的致密化行为。实验数据在三轴压缩与各种加载条件下获得。根据Al 6061粉末的三轴压缩实验数据，提出了一种特殊形式的Cap模型。建议的屈服函数和其他几个屈服函数在文献中实现到一个有限元程序（ABAQUS）进行比较与实验数据的致密化行为的Al 6061粉末在冷等静压和模压。在冷等静压和模压条件下，屈服函数的有限元计算结果与实验数据吻合得很好。
Densification behavior of aluminum alloy (Al6061) powder was investigated under cold compaction. Experimental data were obtained under triaxial compression with various loading conditions. A special form of the Cap model was proposed from experimental data of Al6061 powder under triaxial compression. The proposed yield function and several other yield functions in the literature were implemented into a finite element program (ABAQUS) to compare with experimental data for densification behavior of Al6061 powder under cold isostatic pressing and die compaction. The agreement between finite element calculations from the proposed yield function and experimental data is very good under cold isostatic pressing and die compaction.
