✦ Synopsis

In Fe-10Mn-2Cr-1.5C alloy the superlattice diffraction spots and satellite reflections have been observed by transmission electron microscopy, these results show that the ordering structure and modulated structure have taken place in this alloy. X-ray diffraction proved that austenitic steel in this alloy is more stable than in traditional austenitic manganese steel. Based on this investigation, we consider that the C-Mn ordering clusters were existing in austenitic manganese steel and the chromium could strengthen this effect by linking the weaker C-Mn couples together. These structures may play an important role in the work hardening of austenitic manganese steel.
