      abstract     = {Low-pressure carburizing (LPC) is a recipe-controlled heat
                      treatment process for surface layer hardening. The
                      combination of the process parameters determines the
                      chemical gradients established within the case, the local
                      microstructure and the depth distribution of the resulting
                      process-induced residual stresses. Here, the objective was
                      to quantify the influence of the process parameters on the
                      resulting material state of the case hardening steel AISI
                      5120 (EN 20MnCr5). Therefore, the carburizing and quenching
                      processes were examined using a self-built process chamber
                      specially designed for in situ synchrotron X-ray diffraction
                      experiments. A method for synchrotron X-ray diffraction in
                      reflection geometry was developed to investigate the LPC
                      process. It could be demonstrated that such experiments
                      enable the analysis of microstructural changes, phase
                      transformations and stress evolution at the immediate
                      surface layer with high temporal resolutions. From a
                      material science perspective, the investigations showed,
                      among others, a carbon saturation of the austenite phase
                      within 10 seconds during the boost segments of the LPC
                      process and the formation of compressive residual stresses
                      below -180 MPa after subsequent quenching.},
