When Pd gains or loses hydrogen or deuterium, the lattice expands or contracts causing a change in physical dimension. Under certain conditions, there is an additional expansion that is largely irreversible. Repeated gain and loss of hydrogen caused this excess volume to steadily increase. After all dissolved hydrogen has been removed, the diameter of a rod is found to have increased and the length to have decreased. These changes suggest the creation of micropores and/or dislocations within the metal. Such changes in the ennvironment with Pd metal can alter the local D/Pd ratio, affect the diffusion of impurities and, perhaps, affect the Fleischmann-Pons Effect.
