Bakhit, Babak (author), Dorri, Samira (author), Kosari, A. (author), Mol, J.M.C. (author), Petrov, Ivan (author), Birch, Jens (author), Hultman, Lars (author), Greczynski, Grzegorz (author)We study microstructure, mechanical, and corrosion properties of Zr<sub>1-x</sub>Cr<sub>x</sub>B<sub>y</sub> coatings deposited by hybrid high-power impulse/DC magnetron co-sputtering (CrB<sub>2</sub>-HiPIMS/ZrB<sub>2</sub>-DCMS). Cr/(Zr + Cr) ratio, x, increases from 0.13 to 0.9, while B/(Zr + Cr) ratio, y, decreases from 2.92 to 1.81. As...journal article 2022

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

(author), Hultman, Lars (author), Petrov, Ivan (author), Greene, J. E. (author), Greczynski, Grzegorz (author)Refractory transition-metal (TM) diborides have high melting points, excellent hardness, and good chemical stability. However, these properties are not sufficient for applications involving extreme environments that require high mechanical strength as well as oxidation and corrosion resistance. Here, we study the effect of Cr addition on the...journal article 2021

't Hart, W.G.J. (author), Schra, L. (author)A comparative experimental investigation was done on the advanced plate alloys 7010-T651 from ALCAN and 7150-T6E189 from ALCOA. The mechanical properties, fracture toughness and corrosion properties were determined. The most notable finding was the excellent fracture toughness of alloy 7150-T6E189 combined with a high tensile strength. The...report 1982

't Hart, W.G.J. (author), Schra, L. (author)The engineering properties of PM alloy X7091-T7E69 forgings were compared with those of forgings of the IM alloys 7075-T73, 7175-T736, 7050-T736 and 7010-T736. The properties considered were: strength, fracture toughness, fatigue crack propagation under constant amplitude and flight simulation loading, stress corrosion crack initiation and...report 1982

't Hart, W.G.J. (author), Schra, L. (author)The Al-Zn-Mg-Cu alloy 7050 produced by Alcoa is a typical plate and forging alloy because of its low quench sensitivity. In order to compare this alloy with the earlier tested plate alloy 7010 an experimental programme was performed involving tensile, fracture toughness, and fatigue testing. In addition stress corrosion crack initiation and...report 1980

't Hart, W.G.J. (author), Schra, L. (author)An experimental investigation.was performed on 80 mm thick plate material of 7OIO-T7651 and 7OIO-T73651 developed by Alcan Industries Ltd in U.K. The testing programme involved: tensile tests, fracture toughness, stress corrosion and fatigue tests. For comparison a similar investigation vas carried out on 7075-T7351 Alcoa plate material.report 1979
