Microalloying boron carbide with silicon to achieve dramatically improved ductility
(American Chemical Society, 2014)
Boron carbide (B4C) is a hard material whose value for extended engineering applications such as body armor is limited by its brittleness under impact. To improve the ductility while retaining hardness, we used density ...
Nanotwinning and amorphization of boron suboxide
Recently, researchers discovered that in contrast to isolated twins, periodic twins with nanoscale spacing can dramatically improve mechanical properties. Ceramics engineers now seek to incorporate this “nanotwinning” into ...
Shear-Induced Brittle Failure along Grain Boundaries in Boron Carbide
(American Chemical Society, 2018)
The role that grain boundaries (GBs) can play on mechanical properties has been studied extensively for metals and alloys. However, for covalent solids such as boron carbide (B4C), the role of GB on the inelastic response ...
