The conference Adventures in the Physical Metallurgy of Steels, to be held on July 23–25, 2013, at the University of Cambridge, will be made available live online free of charge to 100 locations around the world. Twenty-five speakers will be selected according to the level of adventure and risk in their work, with no parallel sessions. The conference will accommodate up to 75 additional attendees. The presentations will be published as a special issue of Materials Science and Technology with independent refereeing through the journal’s usual editorial process. The conference, hosted by the Phase Transformations and Complex Properties research group in the Department of Materials Science and Metallurgy at Cambridge, is endorsed by the Materials Research Society.
