Electromagnetic wave-absorbing behavior of soft-magnetic medium entropy alloys with BCC/L21 coherent microstructure

open access: yesMaterials & Design, 2022
Magnetic alloy powders show a great superiority in the balance of permittivity and permeability for electromagnetic (EM) wave-absorption. However, it is necessary to enhance their effective absorption bandwidth (Δf) and impedance matching due to their ...

Entropies in Alloy Design for High-Entropy and Bulk Glassy Alloys [PDF]

open access: yesEntropy, 2013
High-entropy (H-E) alloys, bulk metallic glasses (BMGs) and high-entropy BMGs (HE-BMGs) were statistically analyzed with the help of a database of ternary amorphous alloys. Thermodynamic quantities corresponding to heat of mixing and atomic size differences were calculated as a function of composition of the multicomponent alloys.

Hexagonal High-entropy Alloys

open access: yesMaterials Research Letters, 2014
We report on the discovery of a high-entropy alloy with a hexagonal crystal structure. Equiatomic samples in the alloy system Ho-Dy-Y-Gd-Tb were found to solidify as homogeneous single-phase high-entropy alloys. The results of our electron diffraction investigations and high-resolution scanning transmission electron microscopy are consistent with a Mg ...
