摘要：
In this study, the W (10-20%)-Cu composites were simultaneously fabricated using commercial, graded commercial, and graded jet-milled W powder. The results show that the W-Cu composites prepared with the graded jet-milled W powders have the highest density and best comprehensive performance due to the combined effect of the particle gradation and jet-milling treatment. Particle gradation is employed to increase the packing density of powders, thereby increasing the relative density of the compressed W skeleton, and the rounded powder with narrow particle size distribution after jet-milling treatment is used to reduce the enclosed pores formed during the process of compacting and infiltration. W-Cu composites with a high density of 16.25 g/cm(3) can be directly obtained by conventional compacting at a low pressure of 300 MPa and following infiltration.
