Abstract
Tom Bell’s PhD was on the subject of quenched iron-nitrogen alloys, a system entirely analogous to the iron-carbon system. Even before he received his PhD, he started his career as a lecturer, specialising in the physical Metallurgy of Martensite and Bainite, the two main constituents responsible for hardening in heat treatment. However, his initiation into heat treatment on an industrial scale can be trace back to his appointment in 1970 as a Heat Treatment Fellow by the Heat Treatment Joint Committee for The Iron & Steel Institute, The Institute of Metals and The Institution of Metallurgists, funded by the British Steel Corporation.
