Improvement in the Hydrogen-Storage Properties of Mg<sub>2</sub>Ni by Adding LiBH<sub>4</sub>
Young Jun Kwak, Myoung Youp Song, Ki-Tae Lee
Korean J. Met. Mater. 2024;62(4):299-305.   Published online 2024 Mar 29
DOI: https://doi.org/10.3365/KJMM.2024.62.4.299

Abstract
To improve the hydrogen-storage properties of Mg2Ni, LiBH4 was added by milling in hydrogen atmosphere (reactive mechanical milling, RMM). Mg2Ni-10LiBH4 was prepared with a composition of 90 wt% Mg2Ni + 10 wt% LiBH4. The quantity of released hydrogen (Hr) versus temperature T curve for Mg2Ni10LiBH4 was obtained by heating at.....

Korean J. Met. Mater. 2023;61(3):145-156.   Published online 2023 Feb 24
DOI: https://doi.org/10.3365/KJMM.2023.61.3.145

Abstract
The effects of the electrogalvanizing conditions (a combination of plating current and time) on hydrogen infusion, embrittlement, and corrosion-induced hydrogen embrittlement (HE) behaviors of ultra-high strength steel were examined. A range of experimental and analytical methods, including electrochemical impedance spectroscopy, hydrogen permeation, polarization, and slow strain rate test, were employed...... More
