Abstract

The phase and structural composition of the interfacial zones between the W–С filler and the Fe–C–B–P–Mo matrix of the composite materials was investigated by quantitative metallographic, X-ray, energy dispersive X-ray, and statistical methods. The peculiarities of a structure formation of the interfaces of dissolution-and-diffusion type were explained based on the regular solution formality taking into account that ion Mo creating non-uniformly charged ion cloud around itself are considered as a local disturbance. The ways to control the intension of the interfacial reactions between the filler and the molten binder under infiltration of composite materials have been recommended.
