Abstract This paper summarizes our recent work on the application of high static magnetic fields to the austenite-to-ferrite transformation and the tempering processes in hot-rolled 42CrMo steel. The thermodynamic and kinetic effects of the high magnetic fields on austenite decomposition and the influences of the high magnetic field on carbide precipitation and the matrix recovery during high-and low-temperature tempering are briefly outlined. Insight into these aspects may provide better understanding of the effects of high magnetic fields on diffusional phase transformations and is of both theoretical significance and technical interest.
