This paper presents an experimental and theoretical investigation of the microstructure formation and segregation behaviour of a new austenitic steel based on the Fe‐Mn‐C alloy system. In order to accomplish the simulations, a modification of the model by Cha et al. is introduced. It includes a correction which compensates for artificial solute‐trapping. A good qualitative agreement is found between the simulated 2D microstructures and the corresponding micrographs. Both simulations and experiments show that this alloy is very prone to manganese segregation. The further investigation on this field is scheduled.
