Bulk nanostructured steel with a scale finer than carbon nanotubes, now produced in tonnage quantities


He has done important work on the theory of solid state phase transformations, in particular the prediction and verification of microstructural development in multicomponent steels.

He has made a major contribution to the understanding of the complex bainitic transformation by developing and using thermodynamic theory to show that different modes of transformation have measurable influences on final microstructure.

He has also used theory to design novel steels which should be resistant to wear and impact deformation, work that has helped in large-scale manufacture of new rail steels.

A similar approach has led him to produce a model for the microstructure of the fusion zone of steel welds, which is now widely used in research laboratories and in industry.

He is the author of the sole textbook on the bainitic transformation in steels.
