Mechanisms of palladium plate forming on its one-sided saturation by hydrogen

The investigation of form change of hydrogen-charged palladium plate was fulfilled in a wide temperature and pressures range. It is shown that form change plates develops in two stages. At the first stage of a short time reached a maximal form changing (bend) of the plate. The second, substantially longer stage, there is straightening of plate. Temperature dependence of the maximum bend of a plate submits to the extreme law. At low temperatures, residual stationary bending plate is 20-30 % from size of the maximum bend. With increasing temperature, the reversibility of plate bending increases and at temperature range of 320-350 oC phenomenon is completely reversible. The investigation of cleanly mechanical bend of the plate prove that the cleanly mechanical bends and hydrogen-induced bends of Pd-plate have different physical nature.
