摘要：

We have studied the contact reaction of titanium, chromium, and tungsten borides with titanium We have established that the materials react according to an exothermic solid-phase reaction mechanism with formation of titanium monoboride and diboride. The reaction is limited by diffusion of boron atoms through the layer of titanium monoboride formed. This makes it possible to successfully use reaction to effectively control the process for obtaining composite materials in the Ti - B4C system under self-propagating high-temperature synthesis conditions.
