【Abstract】 In this paper,the material quality engineering analysis of large generator stators is made for high Mn nonmagnetic ZG25Mn18Cr4 steel since their mechanical properties are unqualified. The theory background of tough-strengthening in the high mangnese austenite steel is revised. The technological measures for improving this casting product property quality are proposed. This work and its results manifested well that the product material quality engineering analysis plays an important role in production and scientific technical activities of an enterprise.更多还原
