| Abstract: | The ingredients of yttrium-based heavy rare earth magnesium nodulizing alloys was investigated, as well as their effects to resist nodulization fading and nodular graphite degeneration was test. The result of application in works showed that yttrium-based heavy rare earth magnesium nodulizing alloys have strong effects of desulphurization, nodulization, nodulization fading resistance and nodular graphite degeneration resistance as well as effects to fine matrix structure,reduce chilling tendency,and increase mechanical properties of heavy section castings themselves. |
