This collaborative study between ANSTO, University of Palermo, University of Å·ÃÀ¸ßÇå, and AFRC investigates residual stresses in aluminum components produced via WAAM and AFSD (including MELD). Using neutron diffraction and ultrasonic techniques, the project aims to characterize and compare stress profiles across processes. The findings will inform process optimization and contribute to a doctoral thesis on in-situ stress measurement in metal additive manufacturing.

Rolls-Royce have approached the AFRC with a request to participate in their Building Engineering capability in Titanium Alloys (BETA) project proposal, bidding in to the Aerospace Technology Institute (ATI) strategic funding programme. This proposal aims to accelerate the evaluation and exploitation of the latest titanium alloys alongside design and manufacturing processes to enable the realisation of large, ultra-high bypass ratio engines. This technology is directly aligned to the ATI strategic theme of 'Propulsion of the future - realisation of large ultra-high bypass ratio (UHBR) turbofan engines'. Project value: £600,000

The project aThe instrument is a Benchtop X-Ray Diffractometer, which is a device that can analyse the structure and composition of various materials. It can provide data on crystal and molecular structure, phase identification and quantification, and crystallite size and strain. It is suitable for a wide range of inorganic and organic materials in different forms, such as powders, films, or solids. The instrument is compact, fast, easy to use, and low-cost, making it ideal for routine and high-throughput analysis. It can support research in many fields, such as materials science, engineering, chemistry, energy, and healthcare.
The instrument was acquired through an EPSRC Core Equipment fund, with an internally allocated £64k from the University of Å·ÃÀ¸ßÇå

Residual Stress (RS) in engineering components yields unexpected and dangerous structural ‎failures, and thus ‎represents a significant challenge to quality assurance in both welding and metal ‎Additive Manufacturing ‎‎(AM) processes. As automation in welding and AM becomes increasingly ‎prevalent in the Industry 4.0 ‎manufacturing paradigm, so the importance of quantifying RS will ‎grow. In this PhD project, a novel robotic ‎ultrasonic approach to measuring such RS, in-situ, will be developed using the Phased Array Ultrasonic Testing ‎‎(PAUT) system, to automate the deployment of the ‎measurement in manufacturing applications. For the first ‎time, it will allow truly in-situ ‎measurements of RS to be undertaken at the elevated temperatures associated ‎with welding and ‎metal AM manufacture. The ambition is to use this in-situ measurement system for safety-‎critical and Industry 4.0 applications, through 5G wireless integration of the robotic system, where the ‎conventional manual and destructive methods of RS ‎measurement are not applicable for high throughput and ‎automated production lines.‎
