Structural changes in Pd (Rh, Pt) solid solutions due to3Heformation during tritium storage

3He retention in LaNi5 and Pd tritides: Dependence on stoichiometry, 3He distribution and aging effects

“…Micro structural properties have also been studied, for Pd only, by TEM observations (that is precluded for LaNi 5 due to the strong deformations in the compounds). The details about sample preparations, and characterization techniques used, will not be given here as they can be easily found in the references [7][8][9][10][11].…”

Aging effects on thermodynamics in palladium–tritium system during tritium storage

“…8 shows Van't Holf's characteristics of palladium tritide in this work, where the dispersed points are experimental data, and the dashed and solid lines are linear fit by Eqs. (1) and (2). Enthalpy and entropy of absorption-desorption plateau for unaged and aged palladium tritide can be calculated by Van't Holf's characteristics, and the results are shown in Table 2.…”

“…It has been experimentally and theoretically studied more for the fresh Pd-T system and there are lots of works, but the aging Pd-T system is still less studied because of its radiation. More aging palladium tritide concerns helium behavior in palladium and its release from aging palladium tritide [1][2][3][4][5][6][7][8][9][10]. Nobile et al studied 80 C desorption isotherms for palladium aged up to 755 days.…”

Development of an inter-atomic potential for the Pd-H binary system.

“…Helium (He) is a by-product of the decay of tritium, and the insolubility of He with metals allows He atoms to be retained within the material leading to the formation of nano-scale bubbles that grow as the concentration of He within the metal increases. The development of these bubbles has been observed experimentally within palladium (Pd) tritide alloys [1,2,3], and analytical [4,5,6,7,8] and computational [9,10,11,12,13] models have been developed to study the processes by which these bubbles form, grow and deform the surrounding metal.…”
