摘要
Abstract The reactions of boron carbide with titanium and zirconium carbides have been examined under various conditions. Reactive sintering of the initial mixtures produces a heterophase material based on B4C?MeB2 via a stage of lower boride formation. The reaction completeness is increased by adding boron and boron silicide. The material has a finely divided structure and high hardness (42?45 GPa). Promising mixture compositions have been identified together with ways of optimizing the sintering modes.
