Russell Goodall is a metallurgist with extensive experience in the science of porous metals, and the development of novel alloys of many types. He has worked for over 15 years on the processing and thermal and mechanical characterisation of a range of new materials.
He joined the Department in 2008 from the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland. He obtained his MEng degree from Oxford University and his PhD from the University of Cambridge, before carrying out postdoctoral research at EPFL. After this he returned to the UK as a lecturer at Sheffield, where he is now Professor of Metallurgy.
In 2019, Russell received the Sir Colin Humphreys Education Award by the Institute of Materials, Minerals and Mining (IoM3). This award recognises Russell's contribution to enhancing students' scientific/technological literacy through the teaching or support of materials, minerals or mining topics within 11-19 learning, either in the secondary or further education sectors.
- Research interests
Russell’s main research interests are in the development of new alloys, in particular High Entropy Alloys and alloys with silver, brazing filler metals, the processing, properties and applications of open-celled porous metals, and in mechanical properties of materials in general.
The ability of metallic elements to combine and interact in alloys offers huge potential for materials to be designed and optimised for particular purposes. Within the group we have developed a number of approaches (both theoretical and experimental) which we use to search the vast potential range of compositions to identify alloy formulations with suitable properties. In this regard we explore a wide range of alloys, including those involving refractory elements, transition elements, platinum group elements and low melting point metals. These have potential applications in fields as diverse as metal joining through brazing, to structures that can survive the environment of a nuclear fusion reactor.
Of particular interest in this respect is the behaviour of alloys made of large numbers of elements (typically five or more) combined in similar quantity; for some compositions these can produce single phase alloys with a perhaps unexpectedly simple structure, which are known as High Entropy Alloys (HEA). Within the research group there is effort on both understanding the fundamental formation and properties of this novel alloy class, and in developing HEA and HEA-like compositions for practical applications.
Russell is working on the development of new alloys as part of his RAEng/The Leverhulme Trust Senior Research Fellowship, Novel Strategies for Designing Alloyed Metals; University of Sheffield (NoStraDAMUS).
This work includes the use of the "replication" process to produce samples of open celled aluminium foam or sponge. In this process a preform of pressed or sintered NaCl grains or agglomerates is infiltrated with liquid aluminium, which occupies the spaces between the grains. After solidification, the salt can be dissolved in water to leave just the aluminium, which "replicates" the spaces in the original perform. This gives an open-celled foam structure with well-defined pore size and density. The relatively high thermal conductivity of pure aluminium, combined with its low density and low cost make such materials interesting for applications requiring heat transfer from or to a fluid medium.
Open-cell foams made from other metals such as titanium can have applications as biomedical implants and electrodes, amongst many others. As well as foams (with pores or cells in random locations), the group also works on porous structures with varying degrees of order, such as 3D lattice structures, which are increasingly easy to produce, even at large sizes and with complex designs, using advanced manufacturing techniques.
Current challenges are the assessment of the suitability of processes for practical fabrication of foam parts, the development of methods to allow production of novel foam architectures, the characterisation of both the mechanical and thermal performance of the material and the further optimisation of the properties for certain applications.

Russell has a long standing interest in public engagement and has been a STEM ambassador since 2010. As well as being Chair of the IoM3 Education Committee from 2015-2018, and supporting the activities of the Schools Affiliate Scheme, he has developed and published several papers on practical demonstrations of materials issues using chocolate:
- J. Dean, K. Thomson, L. Hollands, J. Bates, M. Carter, C. Freeman, P. Kapranos and R. Goodall, “Composite Material Design and Materials Selection Practical using Chocolate”, Physics Education, 48 (2013) 465-471

Russell also teaches a module on Public Engagement and Outreach to Doctoral Training Scheme students, supporting them to develop their own outreach ideas. Some of the notable outcomes of this module are the development of a “Materials Monopoly” board, shown at the Cheltenham Science festival and since produced at a larger scale by the Advanced Metallic Systems CDT for distribution throughout the UK, and stop motion animations directed at younger children.
