| Abstract: | influences of rare earth elements on the properties of cemented carbide for mining are studied in this paper. The test results shows that addition of a certain guantity of rare earth elements io certain morphoIogy can increase the service life,bending strength,impact toughness,thermal plasticity and high temperature toughness of cemented carbide for mining,and without obvious influence on its hardness,density and magnetic force. |
