Abstract
A new composition of high-manganese steel with high Mn and low Si steel was studied, evaluating
the austenite stability after different heat treating conditions. In order to determine the phase
transformations and austenite stability, dilatometry experiments were carried out, and the
microstructure was characterized by light optical microscopy, x-ray diffraction, and transmission
electron microscopy. For long holding times at 550°C the precipitation of lamellar cementite emerged
from the microstructure. For very long treatments at this temperature, epsilon martensite was
observed, as a result from the depletion of C by cementite formation and thus the reduction of the
austenite stability.
