Effects of Magnetic Field Intensity on Microstructure and Orientation of Proeutectoid Ferrite in Fe-C Alloy

Article Preview

Abstract:

The effects of the magnetic field intensity on microstructure and crystallographic orientation of proeutectoid ferrite in Fe-0.36C alloy have been investigated. Results show that the amount of the Widmänstatten ferrite decreases with the increase of the magnetic field intensity. The transformed proeutectoid ferrite tends to elongate and align along the field direction due to the magnetic dipolar interaction. This tendency is more pronounced when the field intensity increases. Moreover, the enhancement of the <001> fiber component along the traverse field direction by magnetic field is obvious when the field intensity is stronger.
