Quantitative analyses of ferrite lattice parameter and solute Nb content in low carbon microalloyed steels

The effect of solute Nb on the ferrite lattice parameter in low carbon steels was examined using X-ray diffraction and related to atomic size difference. The concentration of solute Nb in ferrite of a furnace-cooled steel was successfully predicted using the measured coefficient of Nb atoms on the ferrite lattice parameter.
