High-entropy alloy nanoparticles (HEA-NPs) show great potential as functional materials. However, thus far, the realized high-entropy alloys have been restricted to palettes of similar elements, which greatly hinders the material design, property optimization and mechanistic exploration for different ...

Nanoporous High-entropy alloy Liquid metal dealloying Dealloying mechanism Abnormal transformation 1. Introduction High-entropy alloys (HEAs) have been widely studied due to their unique multi-principal alloying system as well as their outstanding physical properties [[1], [2], [3], [4], [5],...
Liquid-phase separation in a CoCrCuFeNi high entropy alloy is evidenced by supercooling method. The CoCrCuFeNi high entropy alloy is supercooled by glass fluxing method with a sample mass about 100 g which allows tensile test at different undercoolings. The microstructure evolution of CoCrCuFeNi ...
For example, one of the most well-studied ternary systems with a stable liquid miscibility gap is the Co-Cu-Fe system [7–17], while with equiatomic additions of Cr and Ni, the CoCrCuFeNi high-entropy alloy solidifies dendritically from a single-phase liquid, as observed by Yeh et al...
Here, we report the first observation of liquid metal expulsion in liquid metal dealloying—liquid Ga rushes out of porous C when the dealloying of Mn–C alloy in liquid Ga is complete. On the contrary, similar to all previous reports, liquid Ga is trapped in porous Pb when In–Pb is ...
Kim, On the strain rate- dependent deformation mechanism of CoCrFeMnNi high-entropy alloy at liquid nitrogen temperature, Mater. Res. Lett. 5 (7) (2017) 472-477.Moon, J.; Hong, S.I.; Bae, J.W.; Jang, M.J.; Yim, D.; Kim, H.S. On the strain rate-dependent deformation ...
high densities, boiling points and chemical stability in addition to excellent conductivity — as the carrier liquid can not only overcome these issues but also make the resulting liquid-metal-based magnetic fluids (LMMFs) highly conductive, substantially expanding the functions of magnetic fluids. ...
Structure of Ga0,7Bi0,3 has been studied by means of X-ray diffraction method reverse Monte鈥揅arlo simulations at different temperatures. Temperature dependences of structure factors and parameters obtained from them are analysed. Most probable interatomic distances, mean and mean root square ...
