Notes:
WC-10Co nanocomposite powders prepared by spray pyrogenation-continuous reductionand carburization technology were consolidated by vacuum sintering plus hot isostatic pressing(HIP). Influences of ball-milled time on properties and microstructure of ultrafine WC-10Cocemented carbide were investigated. The results show that ultrafine WC-10Co cemented carbidescan reach 99.79% relative density, and transverse rupture strength is more than 3750MPa, RockwellA hardness is more than 92.6, the average grain size is less than 440 nm, when ball-milled time is48 hours, ultrafine WC-10Co cemented carbide with excellent properties and fine microstructure isobtained. The optimum ball-milling time is 48 hours
