Ostwald Growth of Carbides in Cyclic Annealing Process of GCr15 Bearing Steel
The spheroidization of the carbide of hot-deformed GCr15 bearing steel was investigated in cyclic annealing process. The results show that most of carbide particles become gradually smaller and more dispersed with the increase of process cycle, however, part of them start to grow for the four cycles, the growth agrees well with Ostwald Ripening Law, and it is not suitable for the further process.
