Boron carbide suffers from a loss of strength and toughness when subjected to high shear stresses due to amorphization. Here, we report that a small amount of Si doping (~1 atomic %) leads to a substantial decrease in stress-induced amorphization due to a noticeable change of the deformation mechanisms in boron carbide. In the undoped boron carbide, the Berkovich indentation–induced quasi
Silicon Carbide Silicon carbide is an important technical ceramic that can be manufactured by a nuer of different methods including hot pressing and reaction bonding. It is very hard, with good wear and corrosion resistance, making it particularly suitable for use as nozzles, liners and kiln furniture.
