Silicon Doped Boron Carbide | Engineering | …

Like most ceramics B4C is very brittle material, limiting its use in some appliions. However recent reports have suggested that doping boron carbide with a small amount of silicon may create a material with much greater ductility with high hardness. We are trying to understand this phenomenon with a joint computational and experimental project.
