Determination of residual stress in nitrided steels with transmission angle-dispersive diffraction JEGOU, Sébastien; BARRALLIER, Laurent (2014)Residual stress analysis with transmission angle-dispersive diffraction is carried out on nitrided steels. It aims evaluating residual stresses within the ferritic matrix but also within secondary phases such as nano-scale ...
JEGOU, Sébastien; BARRALLIER, Laurent; KUBLER, Régis; SOMERS, Marcel (Hanser, 2011)Development and evolution of compressive residual stress during nitriding treatment are studied. A model carbon iron-based alloy Fe-3wt.%Cr-0.35wt.%C was nitrided in gas at 550 °C for different times. Microstructural ...
JEGOU, Sébastien; KUBLER, Régis; BARRALLIER, Laurent; ROCH, François (2009)Nitriding of steels is an important treatment in duplex hardening methods. This treatment is known in the art but some advances still need to be done in terms of residual stress understanding. Although residual stresses ...
JEGOU, Sébastien; KUBLER, Régis; BARRALLIER, Laurent (Trans Tech Publications, 2010)This work deals with the development of residual stresses during nitriding of steels. The main features of a chemico-thermo-mechanical model of nitriding are presented. A micro-macro approach is applied based on volume ...
JEGOU, Sébastien; BARRALLIER, Laurent; FABRE, Agnès (2014)In a previous study, the capability of X-ray diffraction technique to qualify damage occurring during friction had been proven . The purpose of this study is to complete this research in order to develop a method to ...
