EFFECT OF TRACE ELEMENTS WITH ZERO SELF-INTERACTION COEFFICIENT ON CRYSTALLIZATION TEMPERATURE OF IRON CARBON ALLOYS
EFFECT　OF　TRACE　ELEMENTS　WITH　ZERO　SELF－INTERACTIONCOEFFICIENT　ON　CRYSTALLIZATION　TEMPERATUREOF　IRON　CARBON　ALLOYS

The effect of trace elements with zero self-interaction coefficient on crystallization temperature of iron carbon alloys was studied and the mathematic equation was developed based on thermodynamics in the present researeh. With the equation developed in this paper, the effects of nitrogen on crystallization temperature of Fe-3.45C-2.15Si0. 16Mn and Fe-3.45C-2. 15Si-0. 80Mn alloys were discussed.
