Abstract:

In this talk Prof. Withers will give an introduction to the use of time resolved in situ imaging of materials processing and mechanical behaviour in 2D using electron microscopy and 3D by computed tomography. Further by combining these modalities he will show how it is also possible to build up a multiscale picture of materials behaviour across short (<1s) and long (many months) timescales. He will consider examples that span many materials and applications. From the elevated temperature creep of magnesium alloys to fatigue damage in polymer composites. From the structure and degradation of batteries to additive manufacturing and hot isostatic pressing of novel alloys. In particular, he will examine how such approaches can help us better understand degradation processes from corrosion and stress corrosion cracking through to the complex fracture processes associated with hierarchical natural and engineered nanostructured materials. Further, he will examine how these techniques can help to create and validate the performance of multiscale image-based modelling approaches to enable the more intelligent design of materials of the future.

About the speaker:

Phil Withers is the first Regius Professor of Materials and is a Fellow of the Royal Society, Royal Academy of Engineering and a Foreign Member of the Chinese Academy of Engineering and the Indian National Science Academy. In 2016 he helped to set up the Royce Institute for Advanced Materials becoming its first Chief Scientist. He recently established the Defence Materials Centre of Excellence which is hosted by the Royce and brings together 24 different partners, being its Interim Director. His research focuses on imaging, modelling and understanding the behaviour of engineering materials in real time and 3D often in situ under demanding environments. To this end he has pioneered the use of synchrotron and lab. X-ray CT to and combined this with information from electron and neutron beams to shine a light on materials behaviour. He set up the Henry Moseley X-ray Imaging Facility which contains a world-leading suite of X-ray imaging systems for academic and applied research and received the Queens Anniversary Award.
