Y-doped AlCoCrFeNi2.1 eutectic high-entropy alloy with excellent oxidation resistance and structure stability at 1000°C and 1100°C

open access: yes, 2020
In this study, the oxidation behavior of AlCoCrFeNi2.1 eutectic high entropy alloy (EHEA) with/without Y doping at 1000 °C and 1100 °C was reported. The doping of minor Y is crucial to improving the Al2O3 scale adhesion and achieving its durability at ...

Influence of super-gravity coefficient on spatial distribution of solidification structure in Al-14.5Si alloys

open access: yesJournal of Materials Research and Technology, 2021
We reported the influence of super-gravity field on spatial distribution of eutectic structure in Al-14.5Si alloys. The Al-14.5Si alloys were solidified under normal gravity (1 g) and various super-gravity fields (1000 g, 2000 g, 3000 g, 4000 g and 5000 ...

Structure and dynamics of the Ge-Pt eutectic system

open access: yes, 2021
This thesis is devoted to the study of the Pt/Ge(110) system. The Pt/Ge(110) system hosts interesting physics, since after the deposition of Pt on the intrinsically anisotropic Ge(110) surface and subsequent annealing at sufficiently high temperatures,the formation of the 2D material germanene, the germanium analogue of graphene, is observed. Germanene
