The dramatic changes in global manufacturing have greatly increased the demand from UK companies for skilled employees and new operational practices that will deliver internationally leading business positions. The UK is considered to be very strong both in scientific research and in the invention of innovative products within emerging sectors. This conclusion is supported by the fact the UK is a significant net exporter of intellectual property, ranking behind only USA and Japan. The potential of the UK's innovation capacity to create new high-end manufacturing jobs is therefore significant. Maximising this wealth generation opportunity within the UK will however depend on the creation of a new breed of skilled personnel that will deliver next generation innovative production systems. Without relevant research training, production research, r&d infrastructure, and an effective technology supply chain, there will be a limit to the UK's direct employment growth from its innovation capacity, leading to constant migration of UK wealth creation potential into overseas economies. Many emerging sectors and next generation products will demand large-scale ultra precision (nanometre-level tolerance) complex components. Such products include: 1) Next generation displays (flexible or large-scale), activated and animated wall coverings, 3D displays, intelligent packaging and innovative clothing ; 2) Plastic electronic devices supporting a range of low cost consumer products from food packaging to hand held devices; 3) Low cost photovoltaics, energy management and energy harvesting devices; and 4) Logistics, defence and security technologies through RFID and infrared systems. The EPSRC Centre in Ultra Precision is largely founded on the support of SMEs. It is widely acknowledged that manufacturing employment growth in developed manufacturing economies will stem from SMEs and emerging sectors . The supply of highly trained ultra precision engineers to UK manufacturing operations is therefore critically important in order to deliver benefit from any new technologies that arise from the industrial or academic research base within the EPSRC Centre in Ultra Precision.

The EPSRC Centre for Doctoral training in Materials for Demanding Environments will primarily address the Structural Integrity and Materials Behaviour priority area, and span into the Materials Technologies area. The CDT will target the oil & gas, aerospace and nuclear power industrial sectors, as well as the Defence sector. Research and training will be undertaken on metals and alloys, composites, coatings and ceramics and the focus will be on understanding the mechanisms of material degradation. The Centre will instil graduates with an understanding of structural integrity assessment methodologies with the aim to designing and manufacturing materials that last longer within a framework that enables safe lifetimes to be accurately predicted. A CDT is needed as the capability of current materials to withstand demanding environments is major constraint across a number of sectors; failure by corrosion alone is estimated to cost over $2.2 Trillion globally each year. Further understanding of the mechanisms of failure, and how these mechanisms interact with one another, would enable the safe and timely withdrawal of materials later in their life. New advanced materials and coatings, with quantifiable lifetimes, are integral to the UK's energy and manufacturing companies. Such technology will be vital in harvesting oil & gas safely from increasingly inaccessible reservoirs under high pressures, temperatures and sour environments. Novel, more cost-effective aero-engine materials are required to withstand extremely oxidative high temperature environments, leading to aircraft with increased fuel efficiency, reduced emissions, and longer maintenance cycles. New lightweight alloys, ceramics and composites could deliver fuel efficiency in the aerospace and automotive sectors, and benefit personal and vehicle armour for blast protection. In the nuclear sector, new light water power plants demand tolerance to neutron radiation for extended durations, and Generation IV plants will need to withstand high operating temperatures. It is vital to think beyond traditional disciplines, linking aspects of metallurgy, materials chemistry, non-destructive evaluation, computational modelling and environmental sciences. Research must involve not just the design and manufacturing of new materials, but the understanding of how to test and observe materials behaviour in demanding service environments, and to develop sophisticated models for materials performance and component lifetime assessment. The training must also include aspects of validation, risk assessment and sustainability.

It has long been true that our ability to 'see' has progressed hand in hand with our understanding of the world, from our understanding of the very distant (first telescopes to Hubble and the array telescopes) to the very minute (first microscopes to the high performance electron microscopes). X-ray tomography opens up not just 3D imaging but temporal changes too. While X-ray imaging is advancing towards 10nm resolution at synchrotrons and we can image at 50nm in the lab., for engineering materials resolution is not an end in itself. We need to be able to image at the scales that control damage nucleation while at the same time having samples large enough to be of engineering relevance. For example, in many cases samples need to be of millimetre, or larger dimensions, for crack behaviour to be representative of practical behaviours (e.g. R-curve response), but the toughening mechanisms operate at the micron scale. This capital equipment project focuses precisely on this spatial regime, enabling us to follow sub-micron microstructure evolution processes in 3D at timescales of tens of minutes in the lab. The new 3D x-ray imager will enable us to achieve a step jump in our ability to follow degradation and repair processes over time (4D), including: - Self-repairing ceramics and polymer composites - Crack growth in tough hierarchical biomaterials and bio-inspired structures - Coating evolution and sub-surface failure - Charging and discharging of batteries and fuel cells. These applications are important for lighter weight transport, producing energy more efficiently through higher enginer operating temperatures, and the move towards a more electric (lower CO2) economy. Besides these specific studies the equipment will be made available to Uk academics 40% time (>240 days over 3 years). This will allow the improved imaging capability relative to what is already available in the Uk to be applied to a vefy wide range of appplications, from civil engineering through to food science, from device materials through to new bio-scafolds.
