ISS observation of zirconium-vanadium alloy sample on hydrogen absorption.

Comparison of doped combination zirconium-tungsten, zirconium- molybdenum and molybdenum-tungsten on single-wall vanadium oxide nanotube in hydrogen gas adsorption

In this study, doped vanadium oxide nanotubes were evaluated using different software to study the absorption of hydrogen gas. Vanadium oxide nanotubes are one of the options for absorption and storage hydrogen gas. In this research study for the first time, the Monte Carlo simulation was used to investigate the hydrogen gas absorption behavior in molybdenum-tungsten, molybdenum-zirconium and z...

EFFECT OF MISH METAL TYPE ON THE MICROSTRUCTURE AND ABSORPTION/DESORPTION CHARACTERISTICS OF MMNI5 HYDROGEN STORAGE ALLOY

In this article, the effects of Pr and Nd were investigated on the microstructure and absorption/desorption characteristics of MmNi5 hydrogen storage alloy. The alloys were prepared in Vacuum induction furnace and the microstructures and phases were analyzed using scanning electron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDS) and X-ray diffraction (XRD). Hydrogen absorp...

Understanding Hydrogen in Zirconium

Selected examples of the Canadian contribution to the development of understanding of the behavior of hydrogen in zirconium alloys are reviewed. To solve the technical problems faced by the nuclear industry, it was necessary to have values for the solubility and diffusivity of hydrogen in the alloys, the diffusivity needed for the three gradients of concentration, temperature, and stress. With ...

In situ hydrogen loading on zirconium powder

For the first time, various hydride phases in a zirconium-hydrogen system have been prepared in a high-energy synchrotron X-ray radiation beamline and their transformation behaviour has been studied in situ. First, the formation and dissolution of hydrides in commercially pure zirconium powder were monitored in real time during hydrogenation and dehydrogenation, then whole pattern crystal struc...
