Kinetics of hydrogen absorption in transition metals and subsurface bonding
We have modified the kinetic equations for the absorption of hydrogen in transition metals to include the effects of strong subsurface bonding. The new equations show that the subsurface, self-trapped hydrogen acts as a valve for the admission of hydrogen into the bulk. The explanation for a number of experimental facts, not well understood before, neatly follows. Discrepancies between theory a...
متن کاملDFT and HF Studies: Geometry, Hydrogen Bonding, Vibrational Frequencies and Electronic Properties of Enaminones and Their Complexes with Transition Metals
Enaminones are those structures made up three various functional groups including carbonyl, alkeneand amine groups which arelocated along with each other in a conjugate fashion. These compoundsare of much attention due to special characteristics and numerous applications. In the paper, sixvarious enaminone structures were theoretically optimized and after concluding, were compared withequivalen...

متن کاملSubsurface bonding of hydrogen in transition metals: dependence on surface orientation
The calculation of the surface-induced enhancement of the binding energy of hydrogen impurities in transition metals, previously reported for close-packed surfaces, are extended to open surfaces in the fee and bee structures. The effect is found to be stronger for close-packed surfaces than for open ones. Numerical values for the subsurface bonding energy in I% and Pd are given, from which chan...
متن کاملProgress in cold roll bonding of metals.
Layered composite materials have become an increasingly interesting topic in industrial development. Cold roll bonding (CRB), as a solid phase method of bonding same or different metals by rolling at room temperature, has been widely used in manufacturing large layered composite sheets and foils. In this paper, we provide a brief overview of a technology using layered composite materials produc...
