Deoxidation products in Fe-Ti alloys were investigated. It was determined that inclusions formed varied their structure to liquid oxide (it's structure is spinel 2FeO.TiO2 or ilmenite FeO·TiO2), solid solution of Ti3O5 and FeO·2TiO2 and Ti2O3 with an increase of the amounts of titanium added.
Isothermal phase diagram of Fe-Ti-O ternary system at 1500° was established and the following results were obtained.
1) Pseudobrookite and anasovite can form pseudobinary system and they are able to dissolve completely each other.
2) Ti2O3 is able to equilibrate with the metallic phase containing titanium up to 27% and this fact agrees with the result of deoxidation products.
As for deoxidation products of vanadium, it was verified that they appear as spinel FeO, V2O3, V203 and VO with an increase of the amounts of vanadium added. Moreover, FeO - V2O3 changes an amounts of wustite dissolved owing to oxygen partial pressure equilibrated.
