온간성형으로 제조된 Fe-Si 자성코어에 미치는 고분자 바인더의 영향

Abstract

Sintering behavior of W?15wt%Cu nanocomposite powders was investigated. The sintered composite with high heating rate showed a more homogeneous microstructurethan 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.
