Lecture 19, by Professors Wu Kaiming and Ting Ping Hou of the Wuhan University of Science and Technology, China,    in the series "Steel Research: A global journey",  organised by Adreil Wong, Dominik Dziedzic and Steve Ooi to mark the retirement of Harry Bhadeshia. 

Ferrite and a number of carbides in steels are known to be ferromagnetic below their Curie temperatures, whereas dilute austenite is not. Therefore, the imposition of an external magnetic field during the course of transformation favours the ferromagnetic components. The effect of alloying elements is considered in terms of their consequences on the magnetisation of the phases concerned. Fields up to 30 Tesla are explored.
