Abstract

Abstract The effect of a high magnetic field on carbide precipitation in W6Mo5Cr4V3 high-speed steel during low-temperature tempering was investigated. The applied high magnetic field promoted the precipitation of M 6C-type carbides at boundaries and in the grain interior, but maximum spheroidization and refinement occurred for those carbides precipitated at boundaries. Compared with M 6C-type carbides, the effect of high magnetic field on the precipitation behavior of MC-type carbides is much weaker. The high magnetic field hindered M 2C-type carbide precipitation by affecting the Gibbs free energy and increased the microhardness of W6Mo5Cr4V3 high-speed steel at low tempering temperature.
