Effect of heating rate on microstructural homogeneity of sintered W-15wt percent Cu nanocomposite from W-CuO powder mixture

摘要

Sintering behavior of W-15wt percent 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.
