The thermodynamics for preparation of AlV55 by aluminothermic process was analyzed by Fact Sage software and differential thermal analyzer.The results show that the reaction occurs spontaneously with 3 276.61 K of adiabatic combustion temperature and 4 567.06 J·g-1 of unit thermal effect,attributed to a liquid-liquid reaction.The effect of V content on yield rate of products and influence of unit thermal effect on vanadium yield rate were also studied.It is indicated that for AlV55 alloy the elevated V content can reduce the effect of Al8V5 brittle phase and increase the yield rate of products in air atmosphere.The unit thermal effect has a significant effect on vanadium yield rate,with about 96.5% of the maximum vanadium yield rate at 3 367 J·g-1 of the unit thermal effect.
