Precipitation Behaviors of Carbides in High Speed Steel during ESR and Heat Treatment

The microstructure and carbides evolution of high-speed steel after electroslag remelting and solution treatment were studied. The thermodynamic precipitation mechanism of carbides in solid phase was discussed and the characteristic parameters of carbides in different processes were also investigate...
