The amount of inclusions as well as their composition, size and
morphology have a significant effect on the quality of stainless steel.
In order to investigate the inclusions in the production of 316Ti grade
stainless steels, the inclusion compositions were analysed from the
steel melt shop process samples and were compared with thermodynamic
calculations. The results were then used to estimate the influence of
aluminium and titanium contents of the metal on the formation of oxide
and nitride inclusions at different temperatures and contents of oxygen
- A mathematical model have been developed for the nucleation, growth and removal of alumina inclusions.
- A mathematical model have been developed for the precipitation of MnS and TiN during solidification.
