Abstract
Interphase carbide precipitation due to austenite decomposition was investigated by high resolution transmission electron microscopy and atom probe tomography in tempered nanostructured bainitic steels. Results showed that cementite (θ) forms by a paraequilibrium transformation mechanism at the bainitic ferrite-austenite interface with a simultaneous three phase crystallographic orientation relationship. © 2013 Elsevier Inc.
