CARBON AND NITROGEN ACTIVITIES OF MATERIALS OF WELD JOINTS

Popis výsledku v původním jazyce

The demand for higher efficiency of energy production in fossil fired power stations goes to increasing of the working temperatures, which rich up to 625stC now. This limitation is given by creep properties of the materials used for steam turbines and the other parts under long high-temperature exploitation. The most widely used materials for this permanent services remain steels. From thermodynamic points of view, the steels can be thermodynamically treated as Fe-Me-N-C based closed systems where Me means metal elements (Cr, V, Mo), N is nitrogen and C is carbon. Phase diagrams and temperature dependent carbon and nitrogen activities of the steels can be calculated using CALPHAD approach, which is based on semiempirical thermodynamic model of the multicomponent/multiphase system and thermodynamic condition of phase equilibrium. The activities of the all elements can be obtained during mathematical solution. In this contribution, the CALPHAD method is applied for an investigation of th
