Stabilized Chemical Potential Diagrams for Ti-Si-C Ternary System at 1200℃ and Their Applications

The thermodynamic data of Ti-Si-C ternary system are collected and calculated. The equilibrium phase diagram of Ti-Si-C ternary system at 1?200℃ and the estimated unknown thermodynamic data of intermetallic compounds are utilized to calculate stabilized chemical potential and to draw the stabilized chemical potential diagrams of Ti-Si-C ternary system.The stabilized chemical potential diagrams combined with the equilibrium phase diagrams of Mo-Si-C ternary system and the principles of thermodynamic, kinetics, mass-balance can be applied to analyze and predict reactions path of synthesis of in situ Ti 3SiC 2-SiC composites using a solid state displacement reaction.
