| Abstract |
Thicknesses of ε and γ`-iron nitride in bilayer(ε/γ`) compound were estimated using x-ray diffraction. The validity of formulation model was checked by comparing calculations with metallographic analysis of iron nitride compound layer grown on steels with gas nitriding. The thicknesses of ε and γ`-iron nitride formed on SPHC steel estimated by the model using ε(111) and γ`(200) diffraction intensity were 2μm and 1.7μm respectively. These are well matched with the results measured by microscope. The calculated thicknesses of the compound layers grown on low alloy steels well agree to the results measured by microscope. However, the estimated results for high alloy steels are thicker than metallographic analysis. |
