The concepts of phase transformation theory can be exploited to design nanostructured steels that transform to bainite at temperatures as low as 150°C. The microstructure obtained is so refined that it is possible to achieve strength in excess of 2.5 GPa in a material that has considerable toughness (40 MPam1/2). Such a combination of properties has never been achieved before with bainite. A description of the characteristics and significance of this remarkable microstructure in the context of the mechanism of transformation is provided
