Paper Title:
The Effect of Plastic Deformation on the Formation of Different Morphologies of Ferrite upon Cooling
  Abstract

This paper addresses the physical mechanisms of the transformation of deformed austenite into allotriomorphic ferrite and Widmanstätten ferrite. The possible implementation of deformation in currently available transformation models for allotriomorphic ferrite and Widmanstätten ferrite is discussed based on a series of deformation dilatometry experiments. It is concluded that a small amount of deformation already gives significantly faster transformation kinetics and a significant decrease in fraction Widmanstätten ferrite, and that the key to understanding the effect of deformation on transformation lies in the nucleation of allotriomorphic and Widmanstätten ferrite. For Widmanstätten ferrite also the growth needs further study.
