摘 要：<正>Using the microwave sintering technology,the effects of phosphorus（P）additions on the microstructure and properties of the ultrafine WC-10Co alloys were investigated.The experimental results show that with only 0.3wt% P additions,full density WC-10Co cermets were obtained at temperature of 1250℃, which is 70℃lower than that of the undoped counterparts.Lower sintering temperature can result in finer WC grain growth;therefore,the P-doped WC-10Co alloys exhibited higher hardness than the undoped ones.But at the same time,P doping could lead to sacrifice of fracture toughness of WC-10Co cemented carbides.
