Effects of multiple hydrogen absorption/desorption cycles on the mechanical properties of the alloy system palladium/silver (wt% = 10–25)

Changes to the strength, hardness and ductility of a series of well-annealed palladium–silver alloys have been investigated as a function of the number of isothermal hydrogen absorption/desorption cycles the annealed alloy specimens were subjected to. The results indicate that the overwhelming majority of the changes to the mechanical properties occur as a result of the first hydrogen exposure treatment. The degree of change to the mechanical properties of the alloys has been found to be dependent on the silver content of each alloy, decreasing as the silver content increases.
