Kinetics and morphology of the reverse β→α hydride transformation in thermodynamically open Pd–H system

Reverse hydride transformations in the Pd–H system

“…It was shown that → hydride transformations proceed by the mechanism of generation and growth. Results of → hydride transformations kinetic and morphology research were described in [20][21][22] and are also summarized in [19].…”

Various properties of Pd3Ag/TiAl membranes from density functional theory

“…Nevertheless, the hydrogen embrittlement is apt to occur in Pd membranes due to frequent lattice expansion and contraction as a consequence of the well-known α2β phase transition [8], and the hydrogen permeability of Pd is easily deteriorated by the poisoning of several gases such as H 2 S, CO, etc. [9][10][11][12][13].…”

Nanoindentation of palladium β- hydride

“…Hydride transformation products cannot be detected by etching, so their morphology is studied by investigating the development of surface relief on a pre-polished metallographic cross-section in an optical microscope in oblique lighting. 2 It was discovered 3 that during both α→β and βα hydride transformations, the previously polished metallographic section is irreversibly deformed. As a result of hydride phase transformations, metals and alloys strongly harden and all their physical properties change.…”
