Abstract

Electron diffraction and high-resolution transmission electron microscopy show the presence of austenite in a heavily-deformed, initially pearlitic steel. This austenite must have formed as a result of the deformation, and it is shown that it could only originate from a reverse martensitic transformation from ferrite to austenite, stimulated by the high shear strains in the deformation. This reverse transformation could play the role of an additional and novel deformation mechanism in nanocrystalline steels.
