Synergy effects in the deformation response of thermodynamically open metal–hydrogen systems

Abstract: This paper reviews how polycrystalline and amorphous metals respond to the combined effect of a nonuniform force field and a high-intensity hydrogen (deuterium) diffusion flow. It is shown that deformation effects in such thermodynamically open systems result from phase transitions occurring due to changes in the hydrogen (deuterium) concentration. The necessary and sufficient criteria for observing such synergy effects are formulated. It is shown that the deformation response in a nonuniform stress field is a very sensitive means for indicating first and second-order structural phase transitions in metal–hydrogen systems.
