Short-Range Ordering of Carbon in Liquid Alloys of 3D-Block Transition Metals

Research output: Contribution to conferenceAbstractScientificpeer-review

Abstract

The strong interactions between C and 3d-block transition metals (e.g., Cr, Mn, Fe, Co, Ni) were thermodynamically analyzed. The liquid solution properties of binary systems containing C showed significant asymmetry due to the Short-Range Ordering (SRO) of C with the transition metals. Using the Modified Quasichemical Model (MQM) in the pair approximation [1], the C containing binary systems were re-optimized using all available experimental data in the literature. In particular, the partial enthalpy of mixing of C in binary liquid solutions has been scarcely considered by the previous optimization based on the random mixing model. On the other hand, the present model successfully reproduced the partial Gibbs energy and enthalpy of mixing data simultaneously. By considering the SRO with the asymmetric interpolation method, this model can also minimize the ternary or high-order parameters to reproduce the liquid solution properties of the C containing multicomponent systems.
