主　　题：hot-deformed high-carbon chromium cast steel carbide isothermal spheroidizing Ostwald Ripening Law 

摘      要：In isothermal spheroidizing process,the spheroidization and growth of the carbide formed in hot-deformed high-carbon chromium cast steel at high temperature were *** results showed that the spheroidizing growth of carbide proceeds in such a way that the bigger carbide particles swallow the smaller ones,and the short rhabdoid carbides dissolve and are spheroidized by *** the samples were held at 720℃ for more than 3 h,the spheroidization is not *** feature of the process is the size increment and the amount decrement of carbide *** empirical equation for growth rate of carbides was *** volume fraction of carbides keeps *** growth process agrees well with Ostwald Ripening Law.
