Dr Alexander J G Lunt is a lecturer in the Materials and Structures Centre within the Department of Mechanical Engineering at the University of Bath.
Alexander completed his MEng in engineering science at Christ Church, University of Oxford from 2008 to 2012. He then continued at the University of Oxford where he studied for a PhD in microscale mechanical testing from 2012 to 2016. During this period he was one of the youngest people ever to be awarded a stipendary lectureship, also at Christ Church.
Upon the completion of his PhD he took up a senior fellowship at CERN, where he was responsible for establishing CERN's newest microscale materials characterisation suite - the XB540 FIB SEM Laboratory.
He started his lectureship at the University of Bath in January 2019.
He has won numerous awards and scholarships:
- WCE best paper award
- EPSRC scholarship
- Barnes award
- Hooke Prize
- Roach Prize
- Dixon scholarship
- GKN award
Alexander’s main research interests are on the development of microscale mechanical experimental techniques using microscopy and non-destructive techniques. This research topic offers the potential to improve substantially our understanding of material mechanics at the micro-to-nanoscale and has arisen from the significant advances in these technologies in recent decades. He has published widely in the field, including work in Scientific Reports and Carbon, on topics ranging from microscale strain quantification in amorphous materials to the development of thin films for radio frequency applications.
He has significant experience in the micromechanical characterisation of a broad range of materials and systems including ceramics, biomaterials, polymers, metals and composites. In particular he has developed methods to characterise microscale variations in residual stress, fracture toughness and yield strength. He performed a significant amount of FEA and analytical modelling in order to understand better these systems and published articles as well as open source codes in these areas.
Alexander also has a wealth of experience in electron microscopy and Focused Ion Beam (FIB) based techniques. He has been responsible for establishing and running 2 different electron microscopy facilities, with a total installation cost of approximately £1.5 million. As a result, he has developed and published work on multiple new microscale mechanical tests exploiting these systems.
The other avenue of Alexander’s research is based on synchrotron and neutron diffraction. He has been awarded over £50k worth of experimental funding for his studies at the some of the world’s leading facilities (including DLS, ISIS, ESRF and SLS) and has published widely in the field. At present he is particularly interested in the characterisation of strain amorphous materials using pair distribution function analysis.
Academic collaboration is fundamental to the work that Alexander performs and he is always looking to establish new research partnerships. He has also collaborated with numerous European Union projects including the €6 million project ‘iStress’ which was directed towards standardisation of residual stress quantification techniques based on FIB milling.
Alexander’s experiences in the characterisation of machining and interfaces has been particularly helpful in process optimisation and refinement for industry. As a result he has participated in joint projects with Rolls-Royce, Airbus, Rolex, CERN, ITER, Zeiss and Tescan. These studies have resulted in significant technical progress, and the improvement of part characteristics. If similar characterisation would be of interest to you, Alexander is keen to develop new industrial links going forwards.
Alexander is currently the express editor for the Elsevier Journal of Materials and Design.
