The high concentration of substitutional elements in ferrite results in distorting lattice of ferrite and thus the diffraction peaks of ferrite deviate to little Angle.
代位元素在铁素体中的固溶，导致了铁素体晶格的畸变，进而引起了衍射峰向小角度方向漂移。

The bainitic ferrite is BCC lattice when the carbon content in it is below 0.3% and it is BCT lattice when the carbon content is over 0.3%.
