Abstract

In the presented work, evaluation and further investigation of previously derived thermodynamic approach for calculation of surface tension of steel was done. Surface tension of pure iron and real steel grades was measured using the sessile drop method up to 1600 °C. Also, surface tension of iron and steels was calculated using thermodynamic approach. Furthermore, calculated and measured values of surface tension were compared and good agreement with difference cca 10 % (and better) was found. Thermodynamic quantities, which are necessary for this thermodynamic approach, were calculated using Thermo-Calc 2015b software with TCFE8 database.
