About

Martin Strangwood is a senior lecturer and runs the Phase Transformations and Microstructural Modelling Group. His research interests lie in the quantification of structures and properties for a range of materials, relating these to processing conditions, composition and eventual properties.

The physical relationships established are then used with thermodynamic and kinetic models to optimise processing and composition combinations. Much work has been carried out on various grades of steel, although aluminium-, titanium-, nickel- and copper-based alloys also feature. Processing steps investigated include casting (continuous, ingot and ESR), reheating, rolling, forging, heat treatment and welding. 

As well as structural metallic alloys various composites, polymers and ceramics have been studied. The polymers and polymer matrix composite applications are often related to sports such as golf, cricket, cycling, hockey, rowing and running. He has been invited to give many presentations on the use of materials in sports equipment. He has been consulted by a number of sports bodies.

He has published over 200 refereed papers and contributed 10 book chapters.

Qualifications

  • PhD, Cambridge, 1987
  • MA Cambridge, 1988

Biography

Martin Strangwood gained his BA (later MA) in 1984 and his PhD in 1988 both from Cambridge University. His PhD was on Prediction and Assessment of Weldmetal Microstructures, an area that he continued for the following 3 years whilst at AEA Harwell working on a variety of projects including the Sizewell B safety case.

During his time at Harwell he also acted as a tutor for the Open University. He joined the School of Metallurgy and Materials at Birmingham in 1990 and has since supervised 53 PhDs and 8 Masters projects
