N2 - A new high-manganese, low-silicon TWIP steel was studied to evaluate austenite stability after different heat treatment conditions. To determine the phase transformations, dilatometric experiments were performed, the microstructure was characterized by light optical microscopy, X-ray diffraction, transmission electron microscopy. Precipitation of lamellar cementite was observed in the microstructure for extended treatment times at 823 K (550°C). Long isothermal holding at this temperature also caused epsilon martensite formation during cooling, resulting from a decrease in austenite stability due to carbon depletion in the matrix when a quantifiable amount of cementite is formed.
