COMPETING INFLUENCE OF POROSITY AND MICROSTRUCTURE

Porosity Causes Porosity can be present in the form of elongated wormholes or uniformly distributed spherical pores, which can be wholly contained in the weld, or can be surface breaking.

Api5l Part 1of 2a- authorSTREAM Presentation Go Premium Killed The term indicates that the steel has been completely deoxidised by the addition of an agent such as silicon or aluminium before casting so that there is practically no evolution of gas during solidification. Killed steels are characterised by a high degree of chemical homogeneity and freedom from porosity. Fion Zhang/Charlie

Prevention of Scum Formation and Entrapment in High Carbon

Killed steels are totally deoxidised, whereas rimmed steels are only partially deoxidised. The amount of deoxidising agent added to a rimmed steel is usually quite small, so some carbon monoxide bubbles will form in the casting.
