Progress of Research in the action mechanism of grain growth inhibitor for cemented carbide

摘要

Three hypotheses for the grain growth inhibiting mechanism of carbide grain were described in this paper: the dissolution hypothesis, the adsorption hypothesis and the segregation hypothesis. The weakness of these three existing hypotheses has been pointed out. On the basis of analyzing the existing research results of other researchers, this paper proposed a new grain growth inhibiting mechanism: segregation - dissolution hypothesis.
