Discovery of spontaneous deformation of Pd metal during hydrogen absorption/desorption cycles.
A drastic deformation was observed in Pd metal of various shapes after hydrogen absorption and desorption cycles at 150 degrees C at a gas pressure of 1-5 MPa. All of the phenomena observed indicate that some strong internal force is induced spontaneously during hydrogen absorption/desorption cycles to produce a collective deformation so as to minimize the surface.
