Název v původním jazyce

On the influence of chromium and oxygene on phase transition temperatures of Fe-C-Cr-O alloys

Popis výsledku v původním jazyce

The paper deals with the study of phase transition temperatures of pseudoquaternary Fe-C-Cr-O based alloys from RT up to 1600 oC. The influence of chromium and oxygene on shift of phase transition temperatures is discussed. The knowledge of phase transition temperatures is crucial for application purpose and also for basic research related always closely to the applications. The deeper insight in to the knowledge of behavior of simple systems can lead to the enhancement of production of more complex alloys with enhanced properties by simultaneous lower cost production. The paper deals with phase transition temperatures such as: temperature of eutectoid transformation, magnetic transition, alfa-gama transition, solidus and liquidus temperature and peritectic transformation temperature. The relation between shift of phase transitions was confirmed and quantified. Phase transition temperatures were obtained by Differential Thermal Analysis (DTA). The comparison and discussion with calculated phase transition temperatures (IDS - Solidification Analysis Package, TC - Thermo-Calc) was done. In some cases substantial differences between experimental and calculated phase transition temperatures were encountered.
