The effects of micron WC contents on the microstructure and mechanical properties of ultrafine WC-(micron WC-Co) cemented carbides
Journal of Alloys and Compounds(2014)
摘要
•The ultrafine WC–(micron WC–Co) cemented carbides were fabricated.•The addition of micron-sized WC particles can generate the deflection of crack in the extension process.•The addition of micron-sized WC particles can improve the fracture toughness obviously.
