MAPP Lecture Series - Dr Simon Hogg
The MAPP Lecture Series [#MappLecture] began in November 2017 with a lecture by Prof. Richard Leach, University of Nottingham, and will continue in Sheffield in 2019 with regular one-hour lunchtime lectures, from experts in the field of AM. All lectures are open to external attendees and will be followed by lunch and an opportunity to speak with the lecturer.
The eighth lecture in the series will be given on Tuesday 22nd October, in Hadfield Building Lecture Theatre 20 by Dr Simon Hogg, Loughborough University.
Dr Hogg is currently Senior Lecturer in Metallurgy in the Department of Materials at Loughborough University. He graduated with a degree in Materials Engineering from Sheffield Hallam University in 1995, and after a spell working in the materials section of an automotive testing centre, studied for a Ph.D. at Sheffield University on semi-solid processing of high-silicon Al-Si alloys, which he gained in 2001. He then worked as a research assistant at Oxford University on spray formed Al-Mg-Li alloys for aerospace applications until 2006, when he moved to Loughborough. His research interests revolve around using advanced characterisation techniques to investigate microstructure during processing and in-service operation of industrial and novel metal alloy systems.
Processing and Characterisation of High Entropy and Spray Formed Alloys
This talk will focus on characterisation of Cr-Mn-Fe-Ni and Cr-Mn-Fe-Co-Cr high entropy alloys produced using powder routes and an novel Al-Fe-Cr-Ti alloy produced spray forming - a variant of powder metallurgy. The talk will describe a range of different characterisation techniques that have been used, including the use of high resolution electron microscopy techniques and the use of the I11 High Resolution Powder Diffraction beamline at the Diamond Light Source for quantitative characterisation of the microstructure. The talk will also include recent work on the use of localised laser and large area electron beam surface remelting of the Al-Fe-Cr-Ti alloy to show how the microstructure can be locally changed using these techniques.
The lecture will be followed by lunch in the Turner Museum.
