| Popis: | Al-Ti complex deoxidation equilibria in high Cr stainless steels were studied by measuring the thermodynamic behavior of O in the Fe-Cr-Al-O, Fe-Cr-Ti-O, and Fe-Cr-Al-Ti-O melts. The present deoxidation experiments were thermodynamically analyzed along with available data in the literature using Wagner’s formalism. The compatible set of parameters for the multicomponent Fe-Cr-Al-Ti-O system was selected, and its applicable concentration and temperature limits were discussed. The parameter set successfully reproduced the present experimental results and literature data of deoxidation equilibria in the Fe-Cr-Al-O and Fe-Cr-Ti-O alloy melts over the wide Cr concentration up to 40 mass pct at 1823 K to 1996 K (1550 °C to 1723 °C). The validity of the parameters was also checked by carrying out the Al-Ti complex deoxidation experiments with the construction of the predominance diagram for inclusions in the Fe-Cr-Al-Ti-O melts at 1873 K (1600 °C). |
