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.

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.

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

Homogeneity enhancement of oxide additives in boron carbide by precipitation method [PDF]

open access: yesProcessing and Application of Ceramics
This study elucidates the use of the precipitation method to enhance the uniformity of oxide additives in boron carbide ceramics. Achieving a homogeneous distribution of additives is critical, as higher additive content tends to degrade the mechanical ...
