Optimization of gaseous nitriding of carbon iron-based alloy based on fatigue resistance modelling WEIL, Hadrien; BARRALLIER, Laurent; JEGOU, Sébastien; CALDEIRA-MEULNOTTE, Nancy; BECK, Guillaume (Elsevier, 2018)Gaseous nitriding of steels is a well-established thermochemical surface treat- ments that increases the fatigue resistance of treated parts. The present work proposes a modelling of the fatigue life as a function of the ...
Gaseous nitriding behaviour of 33CrMoV12-9 steel: evolution of the grain boundaries precipitation and influence on residual stress development JEGOU, Sébastien; BARRALLIER, Laurent; FALLOT, Guillaume (Elsevier, 2018)The gaseous nitriding behaviour of 33CrMoV12-9 steel was investigated. The co-diffusion of nitrogen and carbon, precipitation at grain boundaries and mechanical properties evolutions (microhardness, residual stresses) are ...
BARRALLIER, Laurent; JÉGOU, Sébastien (A3TS, 2017)Le traitement thermochimique de nitruration est un traitement de surfaces permettant d'améliorer la durée de vie en fatigue des pièces traitées. Les dernières avancées dans ce domaine permettent de relier les paramètres ...
FALLOT, Guillaume; JEGOU, Sébastien; BARRALLIER, Laurent (2014)The evolution of residual stresses during short time gas nitriding of 33CrMoV12-9 steel grade is studied. It aims understanding the influence of nitriding parameters (temperature T and nitriding potential Kn) on the ...
FABRE, Agnès; JEGOU, Sébastien; BARRALLIER, Laurent (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 ...
