Experimental investigation of the hydrogen elasticity phenomenon in the a-PdH<i><sub>n</sub> </i> alloy plate
The phenomenon of hydrogen elasticity and the effect of the hydrogen initial content on the palladium plate form-changing upon one-side additional saturation with hydrogen up to the composition of the a-PdH n alloy at 180°C were studied experimentally. The experiments confirmed that the form-changing of the plate proceeds in two stages. At the first stage, the plate quickly reaches the maximum bending. And at the second stage that is significantly longer, the plate reversibly straightens almost completely. It was found that hydrogen contained initially in palladium impacts on the value of the maximum bending, on the time to achieve maximum bending, on the kinetics and magnitude of the residual stationary form-changing. The physical nature of the established experimental laws was analyzed.
