Abstract: Based on MSC. Marc finite element software, the densification process of single and two-press Cu-Cr powder particles was microcosmic simulated and analyzed. The effects of different pressing methods and friction coefficients on the particle density and morphology of Cu-Cr powder particles were studied. The results show that with the increase of friction coefficient, the densification degree of unidirectional compacted Cu-Cr powder particles is higher. Under the condition of friction coefficient of 0.5, the maximum density of unidirectional compacted Cu-Cr powder particles is 96.4040%. With the decrease of friction coefficient, the densification degree of the two-way compacted Cu-Cr powder particles is higher. Under ideal condition without friction, the densification of the two-press compacted Cu-Cr powder particles is up to 89.1630%. Under the same conditions (friction coefficient and compressive force), unidirectional compaction has higher fluidity and density than bi-directional compaction, and the strain difference of Cu particles is 1.3385. However, the particle size uniformity of bi-directional compaction is better than that of unidirectional compaction. The simulation results are in agreement with the experimental results, which verifies the accuracy of the model.
