Stored energy evolution in both phases of a duplex steel as a function of cold rolling reduction

The influence of cold rolling reduction on stored energy was studied in a duplex steel using neutron diffraction. The austenite stores more energy than the ferrite. In the ferrite, more energy is stored in the gamma-fiber than in the alpha-fiber. In the austenite, the stored energy increases regularly with reduction. (c) 2005 Acta Materialia Inc.
