Abstract
The optimal porosity of carbide frame is 44 ... 52 %. The author explored the kinetics of the process of impregnating of the green carbide frame of titanium carbide by steel 18Cr10NiTi and experimentally found dependence of the rate of impregnation of the distance of 1 cm from the contact surface of the steel with carbide frame. The dependence of the impregnation time from the pressing height was found. The regularities of distribution of grains of titanium carbide in pressing height after impregnation was determined and its dependence on recrystallization of carbide grains through the liquid phase was described.
