Boronizing of CoCrFeMnNi High-Entropy Alloys Using Spark Plasma Sintering

open access: yesJournal of Manufacturing and Materials Processing, 2022
In this study, we investigated the formation of a protective coating on a face-centered cubic high-entropy alloy (HEA). The coating was formed by a diffusion coating method.

Improved Ductility of Boron Carbide by Microalloying with Boron Suboxide [PDF]

open access: yes, 2015
Boron carbide (B_4C) is the third hardest material in nature, but applications are hindered by its brittle failure under impact. We found that this brittle failure of B_4C arises from amorphous shear band formation due to deconstruction of icosahedral ...
