The First Observation of a Shear‐Induced bcc→fcc Transformation in Nanocrystalline Ferrite
Source abstract
Abstract
Ferrite has been transformed to austenite at room temperature in an initially pearlitic steel. This occurs under high shear strain conditions once the alloy has been grain‐refined down to a nanoscale dimensions by high‐pressure torsion deformation. This transformation must have occurred by a martensitic mechanism and plays the role of an additional deformation mechanism for the nanostructured material.
