The role of hydrogen-exposure temperature on the mechanical properties of hydrogen-cycled palladium

Changes in the mechanical properties of palladium that has undergone a cycle of hydride formation and decomposition in the temperature range 323–623K have been characterized. The results show that at all temperatures studied cycling increases the strength and hardness of palladium while decreasing ductility, compared to well-annealed palladium. The extent of the changes in mechanical properties has been found to be essentially independent of cycling temperature up to 473K and dependent on cycling temperature above 473K.
