摘要：

Sintering behavior of W-15wt%Cu nanocomposite powders was investigated. The sintered composite with high heating rate showed a more homogeneous microstructure than that with low heating rate. Microstructural characteristics depending on heating rate were explained by the different sintering, the effect of powder agglomerates, and exuded Cu from agglomerated powders.
