%X Dislocation densities in ductile iron under different processing conditions were determined exactly by X-ray diffraction method and a new profile analysis theory. The relations of dislocation density to chemical composition,austempering temperature, tempering treatment and deformation treatment were analysed. Experimental results indicated that the increase in dislocation density was accompanied by the fining of bainite grain.
