摘要：

The beginning temperature of chemical reaction between Ti and B4C and the production phase after soaking 0.5h at 1600 degreesC were determined by DT and XRD, respectively. The mechanism of chemical reaction was studied by the diffusion couples of Ti-B-4 C. It shows that the diffusion path is Ti/TiC/TiB/TiB2/B4C and the (TiB2+TiC+TiB) triple phases coexist in the Ti-B4C diffusion couples. However, there exist two phases of TiB2 and TiC for the powders of Ti+B4C sintered at 1600 degreesC.
