hydrogen embrittlement of steels is a wide phenomenon that induces a severe economic damage and sometimes even cost of life. Even though there are some suggested mechanisms for this phenomenon, it is not yet possible to predict the time to failure of a component serving under hydrogen presence conditions. By using synchrotron radiation for energy dispersive X-ray diffraction one can characterize the diffusion behavior of the solute hydrogen which is namely the diffusible hydrogen in the metal which is according to some of the mechanisms responsible for the embrittlement phenomenon. In this study the diffusion behavior of hydrogen in supermartensitic stainless steel was studied by means of energy dispersive X-ray radiation.
