锰对铸态奥氏体高铬铸件基体组织的影响

Effect of Manganese on Matrix Structure or As-cast Austenite Higk Chromium Cast Iron

以高铬铸铁磨球为对象，在控制一定ｃｒ／ｃ比的条件下．通过加入适量Ｍｎ，探讨了在厚断面铸件中获得奥氏体基体的可能性，从而为生产铸态奥氏体高铬铁磨球提供了另一条较为经济的途径。

The approach to the probability of obtaining as-cast austenite matrix in thick-section highchromium cast iron grinding balls by controlling Cr/C ratio and alloying with appropriate manganese wasconducted in this paper, A more economical way was found for the production of as-cast austenite high chromiumcast iron grinding balls.
