Abstract
The reactions of boron carbide with titanium and zirconium carbides ha ve been examined under various conditions. Reactive sintering of the i nitial mixtures produces a heterophase material based on B4C-MeB2, via a stage of lower boride formation. The reaction completeness is incre ased by adding boron and boron silicide. The material has a finely div ided structure and high hardness (42-45 GPa). Promising mixture compos itions have been identified together with ways of optimizing the sinte ring modes.
