Abstract

Abstract: In this Paper,interaction coefficients among Al,Ti and C in Al-Ti-C ternary system and actual free energy of Al_3Ti,TiC and Al_4C_3,were calcutated via ternary alloy thermodynamic theory.The rsults show that,at low temperatures,Al_3Ti forms through the reaction of aluminium with titanium,and at high temperatures,the TiC forms hy the reaction of carbon with Al_3Ti.The reaction mechanism was verified by the experimental results.

Key words: thermodynamics, reaction mechanism, Al-Ti-C.system
