Prof. Phil Withers, Manchester University Bio: Professor Philip Withers obtained his PhD in Metallurgy at Cambridge University and took up a lectureship there, before taking up a Chair in Manchester in 1998. His main interests lie in the application of advanced techniques to assess the structural integrity of engineering materials and components. To this end he has built instruments for residual stress measurement and 3D imaging at central neutron and synchrotron facilities, as well as founding a Unit for Stress and Damage Characterisation in Manchester, work for which he was elected to the Royal Academy of Engineering in 2005. In 2007 he became the founding Director of the University of Manchester Aerospace Research Institute linking over 100 academics within the University with the aim of undertaking cross disciplinary research. In 2010 he set up the Manchester X-ray Imaging Facility combining both lab. X-ray scanners and a beamline at the Diamond Light Source for 3D X-ray imaging across scales from 1m to 50nm which he co-directs with Professor Peter Lee. He was awarded the Royal Society Armourers & Brasiers’ Company Prize for pioneering use of neutron and x-ray beams to map stresses and image components in 2010. In 2012 Phil became the Director of the new BP International Centre for Advanced Materials, aimed at advancing the fundamental understanding and use of materials across a variety of oil and gas industrial applications. |

Together non destructive (X-ray) and destructive (serial section electron microscopy) enable us to probe materials behavior across a very wide range of lengthscales and timescales. In this presentation I will describe the multiscale 3D characterization workflows combining macroscale X-ray computed tomography (CT), micro X-ray CT, nanoscale serial section FIB/SEM imaging and analysis, and scanning transmission electron microscopy to study a range of materials degradation and repair processes. This approach allows us to travel down the scales to better understand macroscale damage in terms of the underlying microstructure and to co-visualise structural, crystallographic (EBSD) and chemical (EDS) information. Future workflows and visualization software advances will enable the materials scientist to bring together multiple scales and information or undertake high resolution imaging with a high degree of knowledge of the local context.
Finally, the three pillars of materials science (microstructure-chemistry-performance) are traditionally studied separately in the microscopy suite, the chemistry lab and the mechanical test facility on different samples. Correlative techniques currently allow one to bring them all into registry in three dimensions.
