Abstract
The mechanical and chemical properties of alloy materials strongly depend on their chemical composition. Among them, Mn is an essential alloying element. After adding Mn to the α-Fe matrix, Mn will substitute the position of Fe. In the Fe-C-Mn system, Mn atoms will interact with C atoms in their neighbouring positions, thereby affecting C atoms’ concentration distribution around them in equilibrium. Based on the first principles method, the interaction between the Mn and C atoms in α-Fe and its effect on C atoms’ solid solubility are calculated and analyzed. The results show an attractive force between the Mn atom and C atom at its nearest position. The interaction energy of the two gradually tends to 0 as the distance increases, especially when the distance exceeds 1.5×aα-Fe. The Mn element increases the solid solubility of the C element in the α-Fe matrix.
