中文摘要	The reaction process of combustion, synthesis for TiB2-Ca was investigated in detail using combustion-wave arresting experiment, X-ray diffraction, (XRD) analysis, SEM analysis and differential thermal analysis (DTA). The XRO analysis results for the different parts of the quenched specimen, show that, TiCux intermetallic phase firstly forms with the propagation, of combustion wave, and then T-1.87 B-50 and T-3 B-4 metastable phases come forth due to the diffusion, of B atoms and finally the stable TiB2 phase forms because of the continuous diffusion, of B atoms. The formation, of TiB2 Phase is not, completed by one step, but undergoes several transient processes. M, process of reaction synthesis for Ti-B-Cu ternary system can be divided into three main stages : melting of Cu and Ti, and the formation of Cu-Ti melt andfew TiCux, TiBx intermetallic phases; large numbers of TiCux intermetallic phases formation and some fine TiB2 particles precipitation; and the. TiB2 particles coarsening and the stable TiB2 and Cu two phases formation in the final product.
