Abstract
A diagram of the meltability of the system B4C-SiC-TiB2 is constructed by calculation. The compositions of binary and ternary eutectics melted in an arc furnace are described. The microstructure, microhardness, and strength of an individual grain are investigated. The prospects for using eutectic compositions as abrasives and in structural ceramics are shown.
