TWI project leader Magdalena Nowak-Coventry’s research into grain refinement of Al–Si alloys has been chosen from a selection of more than 1000 papers to win an international award.
The Charles Hatchett Award is presented annually in recognition of the best international research into the science and technology of niobium, and is sponsored by CBMM (Companhia Brasileira de Metalurgia e Mineração) in collaboration with the UK’s Institute of Materials, Minerals and Mining.
The recipients of this year’s award are Madgalena Nowak-Coventry, project leader in the Asset and Fracture Integrity Management group at TWI, Hari-Babu Nadendla, Brunel University London and Leandro Bolzoni, the University of Waikato, whose two papers were chosen from over one thousand that were reviewed as part of the competition process.
The selection process looks for technical excellence and originality, and also considers the social, economic and environmental advantages of any proposed application of niobium.
The winning papers – based on Magdalena’s PhD, ‘Novel grain refiner for Aluminium alloys’ which she completed at Brunel University London prior to joining TWI – are as follows:
- ‘Grain Refinement of Al–Si Alloys by Nb–B inoculation. Part I: Concept Development and Effect on Binary Alloys’, Materials and Design, Vol 66, Part A, (2015), 366–375
- ‘Grain Refinement of Al–Si Alloys by Nb–B inoculation. Part II: Application to Commercial Alloys’, Materials and Design, Vol 66, Part A, (2015), 376–383
The technology explored in the papers is of particular relevance to the use of aluminium in the automotive industry where it is being applied to reducing the weight and increasing the strength of vehicle components.
The award was presented to the winners at a celebration dinner held at the Royal Society of Chemistry, London on 13 July 2016. The following day, Magdalena and her colleagues presented the results of their papers in a seminar, which started a dialogue in the UK supply chain regarding potential applications for the grain refinement technique.
Speaking of her success, Magdalena said: 'I am delighted to win this award, with my colleagues, and look forward to seeing our research applied in a commercial industry environment in the future.'
