2. 1. Thermodynamic Studies of the Fe-Pt System and “FeO”-Containing Slags for Application Towards Ladle Refining

   Author : Patrik Fredriksson; KTH; []
   Keywords : Thermodynamics; Activity; Galvanic cell; Calorimetry; Gas equilibration technique; Iron-platinum alloys; FeO; Slags; Modelling; Ladle;

   Abstract : In the present work, the thermodynamic activites of ironoxide, denoted as "FeO" in the slag systems Al2O3-"FeO", CaO-"FeO", "FeO"-SiO2, Al2O3-"FeO"-SiO2, CaO-"FeO"-SiO2and "FeO"-MgO-SiO2were investigated by employing the gasequilibration technique at steelmaking temperatures. Thestrategy was to expose the molten slag mixtures kept inplatinum crucibles for an oxygen potential, determined by aCO/CO2-ratio. READ MORE

4. 2. Thermal Expansion and Local Environment Effects in Ferromagnetic Iron-Based Alloys : A Theoretical Study

   Author : François Liot; Igor Abrikosov; Peter Mohn; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : The Nobel Prize for Physics 1920 was awarded to C.-E. Guillaume for his discovery of properties of nickel steels. He had previously observed that certain iron-nickel alloys exhibit the Invar effect i. READ MORE

5. 3. Thermodynamic studies of some iron oxide-containing slag systems

   Author : Patrik Fredriksson; KTH; []
   Keywords : ;

   Abstract : In the present investigation experimental measurements ofthe thermodynamic activities of iron oxide in the systems:Al2O3-“FeO”, CaO-“FeO”,“FeO”-SiO2 and, CaO-“FeO”-SiO2 wereperformed by using gas equilibration technique. Theexperimental measurements were performed in the temperaturerange 1823-1923 K for the binary systems and, at 1873 K for theternary system respectively. READ MORE
