Mechanical stabilisation of austenite

S. Chatterjee, H. S. Wang, J. R. Yang and H. K. D. H. Bhadeshia


A theory has been developed for the mechanical stabilisation of plastically deformed austenite by balancing the force which drives the transformation interface against the resistance from dislocation debris in the austenite. The work has been used to explain why very large strains are required to mechanically stabilise certain stainless steels, and also to interpret the subunit mechanism of bainite growth.
