Abstract

In order to investigate the effect of pulse magnetic field on isothermal bainitic microstructure and performance of Cr5 steel, pulse high magnetic field with 1.5T was exerted during isothermal bainitic transformation, continuous cooling + isothermal bainitic transformation and austenitizing + continuous cooling + isothermal bainitic transformation process, respectively. Results showed that, compared with normal isothermal bainitic transformation with the same technology, applying pulse magnetic field during the isothermal bainitic transformation can obviously promote bainitic transformation, the volume fraction of bainite increased by 4.2%, the volume fraction of retained austenite is reduced by 1.7%, and the hardness of Cr5 steel was reduced by 3 HRC.
