TL;DR: It is shown that oxygen can take the form of ordered oxygen complexes, a state in between oxide particles and frequently occurring random interstitials, which lead to unprecedented enhancement in both strength and ductility in compositionally complex solid solutions, the so-called high-entropy alloys (HEAs).
Journal ArticleDOI
Thermal stability and coarsening of coherent particles in a precipitation-hardened (NiCoFeCr)94Ti2Al4 high-entropy alloy
TL;DR: In this paper, the coarsening of L12 precipitates in a face-centered-cubic (fcc) (NiCoFeCr)94Ti2Al4 high-entropy alloy (HEA) at temperatures between 750 and 825
Journal ArticleDOI
Altered ageing behaviour of a nanostructured Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr alloy processed by high pressure torsion
W.T. Sun,Xiao Guang Qiao,Mingyi Zheng,Chao Xu,Shigeharu Kamado,Xiaojun Zhao,Houwen Chen,Nong Gao,Marco J. Starink +8 more
TL;DR: In this paper, the ageing behavior of a nanostructured Mg-8.2Gd-3.8Y-1.4Zr (wt.%) alloy produced by solution treatment followed by high pressure torsion (HPT) was systematically investigated using hardness testing, high resolution high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), elemental mapping, X-ray diffraction (XRD) and XRD line broadening analysis.
Journal ArticleDOI
Microstructural Control via Copious Nucleation Manipulated by In Situ Formed Nucleants: Large-Sized and Ductile Metallic Glass Composites.
TL;DR: A novel strategy to control the precipitation behavior of the austenitic phase, and to obtain large-sized, transformation-induced, plasticity-reinforced bulk metallic glass matrix composites, with good tensile properties, is proposed.
Journal ArticleDOI
Revisiting building block ordering of long-period stacking ordered structures in Mg–Y–Al alloys
TL;DR: In this paper, the 18R LPSO structure in two Mg-Y-Al alloys, in both cast and homogenized conditions, is systematically investigated using atomic-scale high-angle annular dark-field scanning transmission electron microscopy and density functional theory.
