摘要：
The mechanical stability of individual retained austenite grains is studied by nanoindentation combined with electron backscattered diffraction, scanning electron microscope, energy-dispersive X-ray spectroscopy and transmission electron microscopy. The average hardness of retained austenite and ferrite is 7.7 and 3.4 GPa, respectively. The large scatter of hardness distribution in retained austenite may be due to the varied stability and boundary structure of different austenite grains. The mechanical stability of retained austenite increases with Mn content. (c) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
