Matlab code to "Assessment of the compositional requirements to form Fe-Mn-C austenite-martensite composites"

Recently, a new generation of high strength steels was introduced by using a lateral chemical pattern of an austenite stabilizer before quenching from partially homogenized austenite to succeed with fine-scaled microstructures of austenite and martensite. A pearlitic microstructure of ternary Fe-Mn-C is a suitable initial state for this when Mn effectively partitions into the cementite. The Matlab script published here provides an implementation of theoretical considerations on partitioning, negligible-partitioning as well as activity-based local equilibrium conditions based on thermodynamic data. With respect to the description of the physical fundamentals of this code incl. the relevant liteature sources, the users should consult the manuscripts linked to this dataset.
