Abstract

We observed an unexpected bending of a horizontally held palladium plate at 150 $^{\circ}$ C under a small external shearing stress. The deformation was fastest at the nominal composition of PdH $_{0.1 - 0.2}$ , which is in the $α + β$ phase. We also observed that a plate warped back and forth during a cycle of absorption and desoprtion of hydrogen when it was hung vertically, which does not have a reasonable explanation.
