| Abstract Scope |
Surface tension emerges as a critical factor in interfacial interactions, shaping the equilibrium between liquid melts and slag systems, determining meniscus configuration during continuous casting, and influencing the entrapment of particles and gas bubbles at solidifying interfaces. Particularly, the effects of alloying elements and impurities on the surface tension at high temperatures are still not well known. Sulfur is an impurity present in every steel alloy. In the present study, the surface tension of sulphur-containing manganese-boron steels is measured at high temperatures via the Maximum Bubble Pressure (MBP) method. Unlike optical experimental techniques based on metallic drops for surface tension determination, the MBP method is less affected by the evaporation of surface-active elements and the purity of the surrounding atmosphere around the sample. Through this approach, the relationship between surface tension as influenced by surface-active elements and temperature can be evaluated, yielding reliable and pertinent data for this steel alloy. |
