Modeling of the Precipitation Layer by the Method of Finite Elements During the Process of Gaseous Nitriding of Steel 16MnCr5

Authors : Naim Syla, Shukri Klinaku and Fisnik Aliaj

Abstract: Gaseous nitriding process is a diffusion process. This kind of process is described by the differential equation known as the Fick’s second law. Its solutions depend on the condition of integration and the geometry of the problem. For the irregular geometry and complicated conditions, analytical solutions are impossible. In these cases, researchers seek for a solution by approximate numerical methods. One of the well-known methods is the Method of Finite Elements (MFE) and the support software for this method, utilized in this research is the ANSYS program. In the precipitation layer due to the creation of nitrides the strength of the material will increase. In this research, the increase of the strength is experimentally determined and the modeling of Orowan’s stresses is carried out by MFE. In the next step, the obtained curves are compared and as a conclusion researchers see that the theory and the experiment are in agreement.
