Microstructural features induced by a high magnetic field in a hypereutectoid steel during austenitic decomposition

A 12-T magnetic field was introduced during the austenitic decomposition of a high carbon steel at various cooling rates. It was found that the magnetic field applied can reduce the amount of proeutectoid cementite, increase the lamellar spacing of pearlite and decrease the frequencies of low angle misorientations in ferrite. The experimental results of this work prove the shift of the eutectoid point to high carbon side and high temperature side by the application of a magnetic field.
