  • Calculation of the mixing entropy of Sn in a tin-iron bilayer

    • 摘要：

      Based on experimental results and theoretical analysis at different temperatures and time of unit diffusion quantity, the mixing entropy in the reaction process between iron and molten tin, is investigated within the range of 260∼350°C. The mixing entropy is plotted versus the dimensional time, which showed that the difference value of it at different time was an upward trend. At different temperatures, the mixing entropy of the system increased with the temperature, tin atoms diffusing into the matrix gradually becaming greater, so as to there has been a appreciable increase in the values of mixing entropy. In addition, the mixing entropy's increase trend becomes smoothly with the temperature increasing, and the entropy change of the system is decreasing more obvious with the temperature increasing.
