Whether manufacturing an orthopedic joint replacement or an Airbus 380, dozens to thousands of different engineering components are assembled as a system, with each component requiring demanding structural or functional requirements. To achieve these requirements, each component has a hidden world of internal structure, ranging from the nano to micron scale. This nano/micro-structure provides strength, toughness, and functional properties. As material scientists, we tailor these complex internal nano/micro-structures to obtain the best performance, working with mechanical engineers to design macroscopic component shape and function. This talk will describe the new tools synchrotron imaging tools that are being developed, such as 4D X-ray imaging, and how they can be applied to better understanding microstructural evolution, enabling us to develop materials with improved structural and functional properties.


Using aeroengine components as the first example, we will demonstrate how combining 4D synchrotron X-ray imaging and unique nano-precision process replicators can be used to design better materials, together with their processing and failure mechanisms. Using the techniques developed for aerospace applications, we will then look inside the heart of a volcano, capturing the behaviour of magma as it flows, crystallises, and initiates vesiculation.


Using ultra-fast radiography, well look inside the molten pool during laser powder bed additive manufacturing to capture the laser-matter interactions, using the results to tailor the process for optimal performance when printing different materials. Using these insights, we apply low dose 4D imaging to improve the designs of novel orthopaedic implants, helping produce titanium 3D printed components which are now in over 100,000 patients.
