Eivani, A.R. (author), Mehdizade, M. (author), Chabok, S. (author), Zhou, J. (author)Magnesium alloys have many unique properties, mostly benefitting from the low density of magnesium. However, they are not competitive, when compared with other lightweight materials, such as aluminum alloys, particularly in ductility and corrosion resistance. There is a strong need to improve the mechanical properties and corrosion resistance...journal article 2021

Kongshaug, Simen Sørgaard (author), Oseland, Oddbjørn (author), Kanstad, Terje (author), Hendriks, M.A.N. (author), Rodum, Eva (author), Markeset, Gro (author)The alkali silica reaction (ASR) in concrete causes internal localized swelling and micro cracking, which result in expansion and correlated deterioration of the concrete material. The stress state of the concrete is known to affect expansion due to ASR, with an anisotropic stress state giving rise to anisotropic expansion. Similarly, the...journal article 2020
