Phase Transitions in Boron Carbide. [PDF]
Materials (Basel), 2023 The idealized rhombohedral unit cell of boron carbide is formed by a 12-atom icosahedron and a 3-atom linear chain. Phase transitions are second order and caused by the exchange of B and C sites or by vacancies in the structure. Nevertheless, the impact of such minimal structural changes on the properties can be significant.

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

The effect of boron on the amount and type of carbides in chromium white irons [PDF]
Journal of the Serbian Chemical Society, 2002 The effect of boron, in the amounts of 0.26, 0.39, and 0.59 wt.%, on the volume fraction and structure of carbides in Cr white irons was examined. It was demonstrated that the addition of boron can change the microstructural characteristics of white iron
