In this paper, we present an analysis of the transmission of displacement and generated stress field across an interface of a bimaterial specimen, when subjected to an external tensile loading. The bimaterial is composed by stainless steel (316LN) and low alloyed ferritic steel (16MND5). Applying an image correlation technique on SEM in-situ tensile tests, it was possible to evaluate locally the displacement field. The displacement field indicated a strong interdiffusive zone as observed by SEM and microhardness measurements. Using iterative FEM solutions, the behaviour of the materials affected by diffusion was finally deduced.
