Mark Ward is an Associate Professor in the School of Metallurgy and Materials, working at improving materials and processes by applying mathematical modelling, electrical and electronic engineering and more general sensing and control techniques. Research topics include producing titanium, nickel and iron alloys by vacuum arc and electroslag remelting, linear friction and electron-beam welding of aerospace structures, additive manufacturing, and analysis of images and orientation maps.

Mark has had research grants from EPSRC as well as doing purely industrially-funded projects. He teaches engineering mathematics and electronics, and is supervising undergraduate and postgraduate students.

Qualifications

Biography

After his A levels Mark took a gap year working for the “Controls” division of British Gas Midlands Research Station : as a teenager it was exciting to do wind-tunnel tests and to help with experiments on what happens when a valve on a high pressure gas pipeline fails. (A very big flame)

Mark studied Engineering at Cambridge from 1987-1990, specialising in electrical engineering and gained a BA (Hons) “Electrical and Information Tripos”

After two more years with British gas in advanced controls, Mark moved to the IRC in Materials Processing at the University of Birmingham in summer 1992 to undertake research on a state-of-the-art facility for making titanium and other alloys. While working on Plasma Arc Furnace, he undertook a part-time PhD “Sensing and controlling the Plasma Arc Cold-Hearth Refining process”.

As well as researching and experimenting in the area of atomisation, powder production, and spraying of titanium and nickel alloys, for the past 10 years much of his work has been on improving the quality and cost-effectiveness of aerospace materials produced by Vacuum Arc Remelting. This has included developing tomographic techniques to image the distribution of electric current within the process, and combining the results with those from other sensing techniques and CFD models. This received the Institute of Electrical Engineers “Measurement Prize.” in 2003.

Since 2008 Mark has worked on a wider range of topics, including advanced techniques for welding aerospace structures, Durville casting, heat treatment of turbine blades, additive manufacturing, and analysis of images and EBSD orientation maps.
