Tuning the deformation mechanisms of boron carbide …
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 Fibre | Materials Hub
Silicon carbide (SiC), also known as carborundum is an exceedingly hard, synthetically produced crystalline compound of silicon and carbon. It occurs in nature as the extremely rare mineral Moissanite. Until 1929, silicon carbide was the hardest synthetic material known. It has a hardness rating of 9, close to that of diamond. In addition to hardness, […]
