摘要：

(Ti,V)(2)AlC/Al2O3 solid solution composites were prepared by solid state combustion simultaneously incorporating reduction reactions of V2O5 and TiO2/V2O5 with aluminum. Two reaction systems composed of Ti-V2O5-Al-Al4C3 and TiO2-V2O5-Al-Al4C3 powder mixtures were studied. Combustion exothermicity was enhanced by increasing V2O5 and Al, which not only caused an increase in the combustion temperature and reaction front velocity, but also facilitated evolution of the (Ti,V)(2)AlC phase. Between two reaction systems, the Ti-containing samples were more energetic and produced (Ti1-xVx)(2)AlC/Al2O3 composites with x=0.2-0.8. The degree of element substitution was reduced for the samples adopting TiO2, which yielded Al2O3-added (Ti1-yVy)(2)AlC with y=0.4-0.8.
