Thermodynamics of Interactions of Complex Deoxidizers Containing Barium With Oxygen in Metal Melts

Abstract

Thermodynamic aspects of steel deoxidation processes and modification of nonmetallic inclusions in steel with alloys containing barium are studied. Multicomponent charts of component solubility in liquid metal are constructed. It is shown that due to low solubility of barium in metal its deoxidizing effect is minimal. Apparently, barium modifying effect is in its high surface activity
