Abstract

Abstract

The theory of grain growth inhibition by second phase particles has been reviewed and used as a basis to compare the behaviour of various grain refining additives. Attempts have been made to use silica particles for grain refinement in HSLA steels. The theoretical analysis has indicated that high volume fraction of silica particles can form during the solidification process. Small silica particles have also been obtained by the experiment.
