Аннотация
The structure, chemical and phase compositions, and hardness of Fe–Ni–Ti–C–B composites prepared by self-propagating high-temperature synthesis (SHS) were studied. It is shown that, in using Fe, Ni, Ti, C, and B4C powders as the starting materials, which are charged into a steel tube, an integrated multilayer plate consisting of steel shell and composite forms in the course of SHS and subsequent hot compacting. The solid solution of Ni and Ti in γ-Fe is the composite matrix; the TiC, TiB2, Fe2B, Ni3Ti, and NiTi compounds are the strengthening phases. The hardness of composites reaches 57–62 HRC. The internal surface of steel shell is strongly jointed with the composite at the expense of the diffusion of synthesis products into steel.
