【Abstract】 The effect of cerium on structural stability and mechanical properties of cemented carbide has been investigated using dynamic thermal mechanical simulation technology. The results show that the stability of fcc structure in Co binder phase is improved by Ce addition. After thermal mechanical circulation, fcc structure of Co binder phase is preserved mostly. As a result, the mechanical properties are improved.更多还原
