Interaction of hydrogen atoms with metals

Hydrogen selective membranes: A review of palladium-based dense metal membranes

“…This is determined by the tendency of the host metal to either form a solid solution or a stable metal hydride [45]. Examples of metals that exhibit an increase in hydrogen solubility with rise in temperature are Mn, Fe, Co and Ni which are known as endothermic occluders.…”

Non-Pd BCC alloy membranes for industrial hydrogen separation

“…The dissolution of hydrogen into a metal is endothermic [76], yet despite this, the solubility of H in a metal can either increase or decrease with increasing temperature. This behavior is dictated by the tendency for the hydrided metal to form either solid solutions and/or pseudo-metallic ordered hydride phases.…”

A theory of hydrogen trapping in a faulted zone of FCC iron

“…In recent years, a number of investigations on the effects of hydrogen in iron, steel and other metals have been carried out [1][2][3][4][5][6]. Since hydrogen embrittlement is one of the serious problems related to steel when it is exposed to various environmental conditions, there is great interest in the mechanical and kinetic behaviour of the hydrogen-iron binary system.…”
