| 摘 要： | The morphology,structure and distribution of the rare earth compounds in the YG8R.YT5R and YT14Rcemented carbides with additions of trace light rare earths were studied with an analytical electron microscope.The particles of the rare earth compounds in these alloys are all spherical and distribute at interfaces betweenthe Co-cement phase and WC hard phase or(TiW)C solid solution,and in the(TiW)C solid solution.In theYG8R and YTI4R alloys,the rare earth compound is RE_2O_3 with a bcc structure,while in the YT5R alloy.the rare earth compound is RE_2O_2S with a hcp structure.

| Abstract: | The morphology,structure and distribution of the rare earth compounds in the YG8R.YT5R and YT14R cemented carbides with additions of trace light rare earths were studied with an analytical electron microscope. The particles of the rare earth compounds in these alloys are all spherical and distribute at interfaces between the Co-cement phase and WC hard phase or(TiW)C solid solution,and in the(TiW)C solid solution.In the YG8R and YTI4R alloys,the rare earth compound is RE_2O_3 with a bcc structure,while in the YT5R alloy. the rare earth compound is RE_2O_2S with a hcp structure. |
