In situ room temperature tensile deformation of a 1% CrMoV bainitic steel using synchrotron and neutron diffraction
Neutron and synchrotron X-ray diffraction spectra have been acquired during room temperature tensile deformation of a creep-resistant bainitic 1% CrMoV steel, in order to study the evolution of internal microstresses and load-sharing mechanisms between the ferrite matrix and the various carbides. Cementite takes load from the plastifying matrix at the onset of macroscopic plasticity resulting in residual interphase stresses. Single peak fitting indicates an elastic anisotropic behaviour of cementite. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
