| Abstract: | Effects of the addition of the trace rare earth oxides on the physical and mechanical properties of WC-8Ni cemented carbide are studied.By X-ray diffraction, scanning electron microscopy(SEM) as well as transmission electron microscopy,the microstructure of the WC-8Ni alloy containing the rare earths were analysed and distri bution of the rare earths in the alloy,their effects on the texture and structure,and the strengthening mechanism of WC-8Ni alloy were investigated.It has pointel out that the physical and mechanical properties of WC-8Ni with rare earths can come near of up to that of YG8. |
