Details of the new programme of talks with abstracts for the period -October up to Christmas 2019 are shown below. Details of the remainder of the programme in the new year will be added in due course.
All talks, unless otherwise stated, will be in the lecture theatre GC13 and will begin with a buffet at 6pm followed by the talk which begins at 6:30pm. Presentations are normally about 45 minutes long followed by a short question and answer question.
Presidential Address “ Research in the School of Metallurgy and Materials. Alison Davenport – Professor of Corrosion Science and Head of School of Metallurgy and materials.
The talk will focus on key areas of research in the School, including advanced manufacturing of turbine blades at the High Temperature Research Centre, which is joint with Rolls-Royce, the development of battery technologies, and a major focus on recycling of both lithium batteries and rare earth magnets. These activities are underpinned by advanced characterisation both through our partnership with Diamond Light Source and in the School’s Centre for Electron Microscopy, and advanced modelling and simulation.
“Oh, thats not good!” – How two airports were brought to a standstill by metal misbehaviour. Bob Vickery- Senior Investigator of Air Accidents- Air Accidents Investigation Branch (AAIB).
An illustration of the work of the Air Accidents Investigation Branch (AAIB) as shown by two accidents where metallurgy is the major causal factor. In the first case, by a seemingly insignificant event in the history of a component made from 4340M steel which led to its eventual catastrophic failure. It shows how a metallic structure can be adversely affected by the smallest deviation or error in a manufacturing or overhaul process. The second case, where a small quantity of a highly reactive metal was caused to release its latent energy over a very short period of time leading to the near loss of a 180 ton airliner. In both cases the immediate aftermath of the accident brought two major UK airports to a standstill.
“Munition shell composition development in World War 1” Sue Parker – Cleveland Institute of Engineers.
The talk starts with some background to WW1 to place it in context, with an explanation of trench warfare, and the stalemate that was the Western Front. The rules governing the composition of shells had, it seems, been drawn up quite arbitrarily, and used a restrictive acid steelmaking practice with strict Sulphur and Phosphorous levels. Only 6 suppliers were accredited to make shell steels, and the S and P restrictions meant that British iron ore could not be used. Importing ores in a war situation was an added degree of difficulty. Dr John Stead, perhaps the most significant chemist-metallurgist in British 19th century iron and steelmaking, analysed some fragments of German shells that fell on the North East Coast, and discovered that they were shelling us with steel we considered unfit to drop on them. The concern from the MoD was that shells would compress under the firing load, jam in the gun, and maybe explode, killing our own soldiers, and rendering the gun useless. Stead devised a drop weight test to examine the compressibility of various compositions, made in Middlesbrough using the Basic Bessemer process, and British Iron Ore. This practice would have increased the supply of shells at a time when there was a shortage, and reduced the price. Correspondence from the National Archives at Kew details his dealings with the MoD, and the resistance to change. It took 15 months to get Dr Stead’s recommendations implemented.
“UK Steel: the bright future of recycling” André Cabrera Serrenho- Senior Research Fellow- University of Cambridge
UK consumers currently demand around 15 million tonnes of steel per year in final goods. Although the British steel production has fallen to well below this figure, the UK largely exports its steel products and manufactured steel goods at low value, while importing most high-value final good containing steel. Only one sixth of UK final consumption of steel goods is currently made with steel produced in the UK. However, domestic scrap availability is expected to increase, which creates a strategic opportunity to transform the UK steel industry from using imported iron ore to recycling national scrap. The UK has a significant advantage in developing technologies for high-quality, high-volume production from scrap to allow a more complete substitution with primary steel. This transition creates opportunities for technology innovation and is environmentally attractive, reducing the greenhouse gas emissions in producing steel to less than half of those from primary production.
