Investigation of the dependence of phosphorus segregation on grain boundary structure in Fe-P-C alloy: сross comparison between Atom Probe Tomography and Auger Electron Spectroscopy

Abstract : Intergranular segregation in a Fe-P-C model alloy after thermal ageing at 650°C has been examined using Atom Probe Tomography (APT) and Auger Electron Spectroscopy (AES). The specimens were prepared using site-specific method combining focused ion beam (FIB) and Transmission Kikuchi Diffraction (TKD). Grain boundary's five macroscopic degrees of freedom (DOFs) were determined from the TKD map supplemented by 3D APT reconstruction. The phosphorus intergranular segregation values obtained using APT and AES techniques were in excellent agreement and equal to 1.6 ± 0.7 at/nm2 and 1.4 ± 0.5 at/nm2, respectively. The two techniques are complementary for a fully quantitative description. © 2018 Elsevier B.V.
