Bhadeshia was born in Kenya to Indian parents,[6][7] who were carpenters. During the 19th century, many Indian workers emigrated to Kenya for building bridges, railway tracks, shops etc. Bhadeshia's interest in science started when he visited the battery shop where his father worked. He was educated at the Kongoni Primary School.[8] During the time that Kenya was a colony and protectorate of Britain, this was the Nairobi South Primary School, but in 1963 morphed to its new name under the auspices of the Government of Kenya (kongoni is a Swahili word referring to an African antelope). He then went on to the Highway Secondary School, also in Nairobi.[9]
He moved with his family to the United Kingdom in 1970[10] and joined the British Oxygen Company in Edmonton as a technician in their metallurgical quality control laboratory.[11] This allowed him to study part-time at the East Ham College of Technology in London, for the Ordinary National Certificate in Science. He then moved to the quality control laboratory at Murex Welding Processes, and they sponsored him to study at the City of London Polytechnic where he graduated with a Bachelor of Science degree in 1976.[1] Professor Robert Honeycombe was at the time the external examiner for the course at the Polytechnic and encouraged him to join his research group at the University of Cambridge. He was admitted to the University of Cambridge to work on the theory and significance of retained austenite in steels and obtained his PhD in 1980 supervised by David V. Edmonds, in Honeycombe's Steel Research Group.[2] The nature of austenite that is retained depends on the preceding phase transformations – as a research student he focused therefore on unravelling the choreography of atoms when austenite undergoes bainitic or martensitic transformation.
Bhadeshia's research is concerned with the theory of solid-state transformations in metals, particularly multicomponent steels, with the goal of creating novel alloys and processes with the minimum use of resources.[12]
Following his PhD, he worked as a Science Research Council Research Fellow until 1981 and has been part of the academic staff at the University of Cambridge since then. He is the author or co-author of more than 650 published papers in the field of metallurgy[13][14] and several books.[15][16][17][18][19][20][21][22][23]
In the 1990s, he worked with British Steel plc on a carbide-free, silicon-rich bainitic steel that was used for rails in the Channel Tunnel[24] and later on a high-performance armour steel for the British Ministry of Defence.[25]
In 2006, he was awarded the Bessemer Gold Medal by the Institute of Materials, Minerals and Mining for "outstanding services to the Steel Industry".[26] In November 2008, he was appointed the first Tata Steel Professor of Metallurgy following a donation by Tata Steel to endow this chair on a permanent basis at the University of Cambridge[27] and he established and took the lead of the new "SKF University Technology Centre", between SKF and the University of Cambridge to conduct research in the field of the physical metallurgy of bearing steels, over the period 2009–2019.[28]
During 2005–18, as the Founding Director of the Computational Metallurgy Laboratory, he helped create the Graduate Institute for Ferrous Technology at POSTECH[29] in the Republic of Korea.

Bhadeshia has developed a wide range of freely accessible teaching materials on metallurgy and associated subjects.[31] The subject matters cover crystallography, metals and alloys, steels in particular, phase transformation theory, thermodynamics, kinetics, mathematical modelling in materials science, information theory, process modelling, thermal analysis, ethics and natural philosophy.
The resources include lecture notes, slides, videos, algorithms, review articles, books, cartoons, audio files, experimental data archives, image libraries, seminars, examples classes, question sheets and answers, automated learning (MOOCS), and a diverse range of other electronic resources. A YouTube channel (bhadeshia123) contains about 1300 educational videos.[32]
The resources are archived as a permanent record by the British Library in an open access mode. For "outstanding teaching activities", he was conferred the Adams Memorial Membership Award of the American Welding Society during 2007.[33]
Bhadhesia has served as editor for the following journals:
