| Abstract: | High energy ball milling and vaeuum-sinter processing for producing nanoclystalline cemented carbide YG8- RE were studied. Effect of the milling time on granularity and mechanical properties of cemented carbide were also analyzed. And influence of the content additive rare earth and sintering temperature were also studied. These above factors were optimized by using experimental techniques such as density test, hardness test, metallographic examination and SEM and gains nanocrvstalline YGS-RE with higher mechanical properties. |
