Design of Particulate-Reinforced Composite Materials [PDF]

open access: yesMaterials, 2017
A microstructure-based model is developed to study the effective anisotropic properties (magnetic, dielectric or thermal) of two phase particle-filled composites. The Green’s function technique and the effective field method are used to derive theoretically the homogenized (averaged) properties for a representative volume element containing ...

NdB6 ceramic nanoparticles: First principles calculations, mechanochemical synthesis and strain engineering

open access: yesJournal of Materials Research and Technology, 2023
Borides are usually hard and brittle materials; however, we report the synthesis of superplastic nanostructured NdB6 ceramic powders, counter to the conventional wisdom that borides are always brittle. We investigate that through strain engineering, NdB6
