Abstract

High-pressure technology has been used to prepare dense, fine-grain specimens of TiB2 at temperatures as low as 1600°C., as compared to temperatures of the order of 2300°C which are required to prepare dense, coarse-grain specimens by vacuum-sintering. Experiments were performed to describe the temperature and the pressure coefficients of the rate of densification and the effect of temperature and pressure on grain growth. Fully dense specimens of TiB2 can be fabricated without significant grain growth. A mechanism for densification under these extreme experimental conditions is suggested.
