摘要
A computer program called TKCALC(thermodynamic and kinetic calculation) has been successfully developed for the purpose of phase equilibrium calculation and diffusion simulation in ternary substitutional alloy systems. The program was subsequently applied to calculate the isothermal sections of the Fe Cr Ni system and predict the concentration profiles of two γ/γ single phase diffusion couples in the Ni Cr Al system. The results are in excellent agreement with THERMO CALC and DICTRA software packages. Detailed mathematical derivation of some important formulae involved is also elaborated.
A computer program called TKCALC( thermodynamic and kinetic calculation) has been successfully developed for the purpose of phase equilibrium calculation and diffusion simulation in ternary substitutional alloy systems. The program was subsequently applied to calculate the isothermal sections of the Fe-Cr-Ni system and predict the concentration profiles of two gamma/gamma single-phase diffusion couples in the Ni-Cr-Al system. The results are in excellent agreement with THERMO-CALC and DICTRA software packages. Detailed mathematical derivation of some important formulae involved is also elaborated.
