| Abstract: | The ultra-coarse grain cemented carbides with outstanding performance was developed by using WC powder with good crystal integrity through controlling the milling time,weight ratio of ball and powder,and keeping original carbon content of the WC powder.The results show that the WC-Co hard alloy with grain size of 8μm and excellent physical properties are manufactured by using WC powder with good crystal integrity and Fsss of 30 μm. |
