An investigation of sintering kinetics of boron and boron carbide is presented. The in6uence of the powder size distribution on the temperature dependence of sintering, on reaching a high 5nal density, and on gaining a homogeneous grain size has been shown. The results on the -rhombohedral usage in
Boron carbide based materials (B C-Me IV-VI V B y ) were obtained by pressureless sintering at 2150-2250ยฐC in the presence of some transition metal (IV-VI group) carbides (Me IV-VI V C y , where Me is Ti, V, Cr, and W). The structural and mechanical (micro hardness, abrasive wear resistance) propert
