摘要：
A cold rolled low carbon steel has been annealed at low temperatures (300-500 degreesC) in order to promote recovery without interaction with recrystallization. It has been shown that the recovery process can be monitored by means of non-destructive magnetic techniques using coercive field (H-c) measurements. Transmission electron microscopy and electron backscattering diffraction (EBSD) observations were carried out in order to investigate the microstructural changes associated with the measured decrease in H-c produced by the recovery. The EBSD image quality maps show that on a microstructural scale, the cold work stored energy is distributed heterogeneously among different texture components, in agreement with previous studies. Recovery mainly affects the {1 1 1} gamma-fibre orientations, leading to the formation of well defined subgrains. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
