The formation and dissolution of the Cr‐rich M7C3and M23C6carbides in an Al‐alloyed Fe–17Cr–9Ni–6Mn–4Al–0.42C (mass%) austenitic stainless steel are investigated by differential scanning calorimetry (DSC) measurements and correlative scanning electron microscopy (SEM)‐based examinations. The formation of M23C6during DSC heating at a rate of 50 K min−1results in the occurrence of a weak exothermic peak. This peak is followed by two endothermic peaks appearing at higher temperatures in the solid state. The peaks in the approximate temperature ranges 1140–1230 °C and 1290–1315 °C are attributed to the dissolution of M23C6and M7C3carbides, respectively. DSC measurements are also conducted for compositional modifications of the reference alloy. The course of precipitation and dissolution reactions remains unchanged by the removal of Al from the chemical composition. Furthermore, an alloy containing lower Cr and C concentrations compared to the reference alloy do not exhibit the endothermic peak due to the dissolution of M7C3carbides, indicating its absence in the microstructure.
