Metallic materials are indispensable to modern human life. From everyday items such as aluminium drinks cans, to advanced applications like jet engine turbine blades and the pressure vessels of nuclear reactors, the positive social impact of metals is difficult to overstate. Yet despite major advances in our understanding of the manufacture and properties of metals, significant challenges remain. Constructing the next generation of electric cars will require improved lightweight alloys and joining technologies. Development of fusion power plants, which will provide near-limitless carbon-free energy, will require the development of advanced alloy systems capable surviving the extreme environments found inside reactors. For the next generation of hypersonic air and space vehicles, we require propulsion systems capable of over Mach 5. Alloys will need to survive 1800 degrees Celsius, be made into complex shapes, and be joined without losing any of their properties. Overcoming these challenges by improving existing metallic materials, developing new ones, and adapting manufacturing methods, then the benefits will be substantial. Now is a particularly exciting time to be involved in metallurgical research and manufacturing. This is not only because of the kinds of compelling challenges specified above, but also because of the opportunities afforded by the emergence of new advanced manufacturing technologies. Innovative techniques such as 3D printing are enabling novel shapes and design concepts to be realised, whilst the latest solid-state processes allow for the design and production of bespoke alloys that cannot be made by conventional liquid casting techniques. Industry 4.0, or the fourth industrial revolution, provides opportunities to optimise emerging and established technologies through the use of material and process data and advanced computational techniques. In order to fully exploit these opportunities, we need to understand the complex relationships between the processing, structure, properties and performance of materials, and link these to the digital manufacturing environment. To deliver the factories of tomorrow, which will be critical to the future strength of UK plc and the wider economy, industry will require more specialists with a thorough understanding of metallic materials science and engineering. These metallurgists should also have the professional and technical leadership skills to exploit emerging computational and data-driven approaches, and be well versed in equality and diversity best practice, such that they can effect positive changes in workplace culture. The EPSRC Centre for Doctoral Training in Advanced Metallic Systems will help to deliver these specialists, currently in short supply, by recruiting and training cohorts of high level scientists and engineers. Through collaboration with industry, and a comprehensive training in fundamental materials science and computational methods, professional skills, and equality and diversity best practice, our graduates will be equipped to become future research leaders and captains of industry.

Forming components from light alloys (aluminium, titanium and magnesium) is extremely important to sustainable transport because they can save over 40% weight, compared to steel, and are far cheaper and more recyclable than composites. This has led to rapid market growth, where light alloys are set to dominate the automotive sector. Remaining globally competitive in light metals technologies is also critical to the UK's, aerospace and defence industries, which are major exporters. For example, Jaguar Land Rover already produces fully aluminium car bodies and titanium is extensively used in aerospace products by Airbus and Rolls Royce. 85% of the market in light alloys is in wrought products, formed by pressing, or forging, to make components. Traditional manufacturing creates a conflict between increasing a material's properties, (to increase performance), and manufacturability; i.e. the stronger a material is, the more difficult and costly it is to form into a part. This is because the development of new materials by suppliers occurs largely independently of manufacturers, and ever more alloy compositions are developed to achieve higher performance, which creates problems with scrap separation preventing closed loop recycling. Thus, often manufacturability restricts performance. For example, in car bodies only medium strength aluminium grades are currently used because it is no good having a very strong alloy that can't be made into the required shape. In cases when high strength levels are needed, such as in aerospace, specialised forming processes are used which add huge cost. To solve this conundrum, LightForm will develop the science and modelling capability needed for a new holistic approach, whereby performance AND manufacturability can both be increased, through developing a step change in our ability to intelligently and precisely engineer the properties of a material during the forming of advanced components. This will be achieved by understanding how the manufacturing process itself can be used to manipulate the material structure at the microscopic scale, so we can start with a soft, formable, material and simultaneously improve and tailor its properties while we shape it into the final product. For example, alloys are already designed to 'bake harden' after being formed when the paint on a car is cured in an oven. However, we want to push this idea much further, both in terms of performance and property prediction. For example, we already have evidence we can double the strength of aluminium alloys currently used in car bodies by new synergistic hybrid deformation and heat treatment processing methods. To do this, we need to better understand how materials act as dynamic systems and design them to feed back to different forming conditions. We also aim to exploit exciting developments in powerful new techniques that will allow us to see how materials behave in industrial processes in real time, using facilities like the Diamond x-ray synchrotron, and modern modelling methods. By capturing these effects in physical models, and integrating them into engineering codes, we will be able to embed microstructure engineering in new flexible forming technologies, that don't use fixed tooling, and enable accurate prediction of properties at the design stage - thus accelerating time to market and the customisation of products. Our approach also offers the possibility to tailor a wide range of properties with one alloy - allowing us to make products that can be more easily closed-loop recycled. We will also use embedded microstructure engineering to extend the formability of high-performance aerospace materials to increase precision and decrease energy requirements in forming, reducing the current high cost to industry.

Metallic materials are used in an enormous range of applications, from everyday objects, such as aluminium drinks cans and copper wiring to highly-specialised, advanced applications such as nickel superalloy turbine blades in jet engines and stainless steel nuclear reactor pressure vessels. Despite advances in the understanding of metallic materials and their manufacture, significant challenges remain. Research in advanced metallic systems helps us to understand how the structure of a material and the way it is processed affects its properties and performance. This knowledge is essential for us to develop the materials needed to tackle current challenges in energy, transport and sustainability. We must learn how to use the earth's resources in a sustainable way, finding alternatives for rare but strategically important elements and increasing how much material we recycle and reuse. This will partly be achieved through developing manufacturing and production processes which use less energy and are less wasteful and through improving product designs or developing and improving the materials we use. In order to deliver these new materials and processes, industry requires a lot more specialists who have a thorough understanding of metallic materials science and engineering coupled with the professional and technical leadership skills to apply this expertise. The EPSRC Centre for Doctoral Training in Advanced Metallic Systems will increase the number of metallurgical specialists, currently in short supply, by training high level physical science and engineering graduates in fundamental materials science and engineering in preparation for doctoral level research on challenging metallic material and manufacturing problems. By working collaboratively with industry, while undertaking a comprehensive programme of professional skills training, our graduates will be equipped to be tomorrow's research leaders, knowledge workers and captains of industry.
