摘要：

The variation in the equilibrium compositions of austenite and titanium-niobium-carbonitride precipitates in Fe-Ti-Nb-C-N-Mn-Si-Mo is considered over a range of temperatures between 1050 and 1500 K and for an alloy composition which is typical of ultra-low carbon titanium-niobium microalloyed steels. The Kohler temperature dependent-subregular solution model is used to describe the austenite phase. The (Ti,Nb) (C,N)//x precipitate phase is described by the Hillert-Staffansson sublattice model for a four-component solution, with components mixed in pairs.
