why quantification of inclusions provides confidence

Endogenous micro inclusions are formed by the physical-chemical effects that occur during the melting and solidification process.They can be formed from the oxygen and sulphur remaining after the deoxidation and desulphurization process or through reoxidation,see fig.3a and 3b.

The different types of manganese sulphide (MnS) inclusions

The type of MnS inclusions in wrought steels depends on the type of sulphide formed in the original cast steel.Type I MnS inclusions are much harder than the other types.During rolling,type I MnS deforms to a 'lozenge' shape.Any silicates usually deform more,ending up at the tips of the lozenge.These two features can be seen in Fig.1a.The Relationship Between MnS Precipitation and theAbstract The relationship between MnS precipitation and the induced nucleation effect of Ti-bearing inclusions has been analyzed using SEM and EDS.In comparison with a non-treated sample,it can be seen that the Ti treatment leads to the oxide evolution from Al-Mn-Si-O to Ti-Al-Si-Mn-O.Moreover,it was found that sulfur congregates around both types of oxide,which is attributed to the MnS The Relationship Between MnS Precipitation and the Induced Abstract The relationship between MnS precipitation and the induced nucleation effect of Ti-bearing inclusions has been analyzed using SEM and EDS.In comparison with a non-treated sample,it can be seen that the Ti treatment leads to the oxide evolution from Al-Mn-Si-O to Ti-Al-Si-Mn-O.Moreover,it was found that sulfur congregates around both types of oxide,which is attributed to the MnS
