摘要：

Interrupted cyclic deformation tests up to 20% of fatigue life were performed on electropolished specimens of a thermally aged superduplex stainless steel. Crystallographic orientation results obtained by electron back-scattering diffraction analysis allowed to determine the individual orientation of each individual grain as well as the plastically active slip systems. Electron back-scattering diffraction results demonstrate the requirement for the accomplishment of several conditions for a slip system to become active. These conditions were found to be different for austenite and ferrite. (C) 2004 Elsevier B.V. All rights reserved.
