THERMO PROFILE ANALYSIS OF (Fe-Ni-Cx (X=0.3-0.5), (Fe-Cr-Cx (X=0.3-0.5) SYSTEMS USING PROPERTY MODULE CALCULATOR AND CALPHAD METHOD.
The paper shows the thermodynamic study of alloy Fe-Cr-C, Fe-Ni-C system using modeling and simulation based tools. The thermo-calc software with Calphad method is utilized for calculations with FeDemo databases. The calculation shows modeling and simulations of the alloys at (1900K-2000K) temperature range. The atmospheric pressure is kept constant 106pascal. The active phase at 1900K is liquid phase with 0.36381 mass percent of Cr, 0.29667 of Fe and 1.00 for C compositions with the total Gibbs energy of -49493.08959j/mol. The withstanding phase is graphite with the thermal expansion coefficient of 0.85021m3 and the 1.00 for C. As seen from the table of diffusion simulations, at the time 30 seconds, the mass percent of the carbon varies as from 0.15211-064.the alloy shows the less activity of carbon in the highest temperature in the Fe-Ni-C alloy system. The highest T-zero is noted 1184.63794 of value. The temperature is noted 500-3000K in the Fe-Cr-C system. The alloy shows the less solubility of the carbon at low temperature, while results the great alloying at higher temperature in the Fe-Ni-C system with T-zero of1184.22907 values with temperature period of 500-3000K .
