| 摘 要： | Microstructures and crack extending characteristic of the YG8R,YT5R and YT14R hard alloysadding a trace cerium were studied by AEM and HVEM with a tensile holder.In the hard alloys addingcerium,the compounds of Ce_2O_3 or Ce_2O_2S could be formed,extending of stacking faults and transforma-tion from fcc Co to hcp Co were suppressed,volume fraction of fcc Co in the alloys was increased,andstrength of Co and(TiW)C phases and grain boundaries were raised.Plastic deformation in Co phase nearedges of the tensile cracks was more strong,and the tensile cracks could pass through some smaller WCgrains.

| Abstract: | Microstructures and crack extending characteristic of the YG8R,YT5R and YT14R hard alloys adding a trace cerium were studied by AEM and HVEM with a tensile holder.In the hard alloys adding cerium,the compounds of Ce_2O_3 or Ce_2O_2S could be formed,extending of stacking faults and transforma- tion from fcc Co to hcp Co were suppressed,volume fraction of fcc Co in the alloys was increased,and strength of Co and(TiW)C phases and grain boundaries were raised.Plastic deformation in Co phase near edges of the tensile cracks was more strong,and the tensile cracks could pass through some smaller WC grains. |
