Abstract  The deoxysulphurization constant of Y and Y oxysulphide standard free energyof formation vs temperature have been determined in liquid Ni.(?)(?)After calculation by thermodynamic analysis,it was resulted that the equilibriumspace diagram for[Y]-[S]-[O]system and a_O-a_S equilibrium phase diagram in liquidNi are presented.Thus,the subsequence and type of the inclusion formation maybe predicted by them.And the formula controlling the morphology of inclusionformed in liquid Ni by Y addition,as well as the relationship between the Y ad-dition and the content of O_2 and S are also given.
