Abstract Scope |
The current heat treatment processes used in the steel industry are highly energy intensive and environmentally damaging. Innovative induction-coupled thermomagnetic processing (ITMP) is a promising, energy-efficient alternative, where the incorporation of a high static magnetic field improves the microstructural and mechanical properties of steel by altering the phase equilibria and transformation kinetics. Literature indicates that there are magnetic field-induced alterations to the solubility of carbon, but the information available on ITMP is insufficient to engineer improved steel heat treatments. The current investigation uses scanning electron microscopy and electron backscatter diffraction to examine the phase development and morphology of martensite and pearlite in binary Fe-C alloys processed under varied temperatures and magnetic field strengths. In addition, the role of the field in microstructure development, especially in the preferential formation of martensite variants, is discussed. |
