Influence of Oxygen Activity, during Melt and Casting, on Metallurgical Quality of Ferrous Alloys
Pecina, Vladimír ; Stránský, Karel (referee) ; Elbel, Tomáš (referee) ; Šenberger, Jaroslav (advisor)
Casting of test castings from low – carbon steel with different deoxidation degrees. Oxygen activity measurement in castings – from the temperatures over liquidus to solidification of metal. Analysis of chemical composition of inclusions. Calculation of thermodynamic equilibrium between oxygen activity and aluminium, silicon and manganese activities in unalloyed steel. Estimation of conditions for the course of carbon reactions in studied casting.
