摘要
本文通过稀土对不同晶粒度硬质合金中WC相的影响研究,结合稀土对合金中碳的影响,首次提出稀土对硬质合金的WC晶粒度影响由二个细化作用和一个促进长大作用共同决定.
This paper has been made that the research of rare earth elements on WC gain size and carbon in cemented carbide.first prements that the Influence of rare earthg elements on V/Cgfrain size in cemented carbide is all together decided by two finely disintegrated role and one precipitate growth role.
