Résumé

At elevated temperature (550°C) intergranular creep cracks have been observed in thermally and environmentally aged 316H stainless steel. To improve the understanding of mechanisms responsible of creep cracking, micromechanical experiments are proposed. An identification procedure of the crack tip position based on kinematic measurements is presented. Finite element simulations of intergranular cracks in bycristals have been performed and used as test fields to deform experimental images and to validate the image processing used for the identification.
