Controlled High-Temperature Sintering of Boron Carbide [PDF]

open access: yesMATEC Web of Conferences, 2019
The paper discusses the boron carbide properties. Two methods are used to examine and control the sintering process of micro/nano boron carbide. For achieving sintering is used a Tammann furnace.

Breaking the icosahedra in boron carbide [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance The extraordinary hardness of boron compounds is related to their internal structure, which is comprised of 12-atom icosahedra arranged in crystalline lattices. In these hierarchical materials, the icosahedra are easy to image with EM, but individual atoms are not.

Thermophysical properties of austenitic stainless steel containing boron carbide in a solid state

open access: yesMechanical Engineering Journal, 2021
In a core disruptive accident scenario, boron carbide, which is used as a control rod material, may melt below the melting temperature of stainless steel owing to the eutectic reaction with them.

Interaction of ZG-refractory with mold flux and ambient air

open access: yesChimica Techno Acta, 2014
Zirconia graphite refractory is used in continuous casting of steel. Slag corrosion resistance influence on time of casting. With factorial experiment 25-1 influence mixture of refractory (content of graphite, silicon carbide, boron carbide) on oxidation

Amorphization Mitigation in Boron-Rich Boron Carbides Quantified by Raman Spectroscopy

open access: yesCeramics, 2020
Boron carbide is an extremely hard and lightweight material used in armor systems. Upon impact above the Hugoniot elastic limit (HEL), boron carbide loses strength and suddenly fails. Atomistic models suggest that boron-rich boron carbides could mitigate

Structural and component characterization of the B4C neutron conversion layer deposited by magnetron sputtering

open access: yesNuclear Engineering and Technology, 2023
Neutron conversion detectors that use 10B-enriched boron carbide are feasible alternatives to 3He-based detectors. We prepared boron carbide films at micron-scale thickness using direct-current magnetron sputtering.
