Abstract

Controlling structure, form and function for engineering alloys processed by additive manufacture (AM) is essential if we are to reduce secondary operations such as HIP or heat treatment.

There are however, challenges in exerting this degree of control. Presently AM systems operate using "fixed" processing parameters and monitoring, where performed, tends to focus on the movement, as a result of thermally induced stress, of components during the build or on simple detection of defects.

Within the MAPP EPSRC Future Manufacturing Hub (Sheffield, Oxford, Manchester, Leeds and Imperial College London) we are seeking to develop such an approach.

To facilitate this, in this PhD research we will combine In-process and In-situ characterization and measurements, employing novel in-process measurements (High speed, High Resolution Thermal imaging, hyper-spectral imaging, mass spectrometry etc.) with beam-line x-ray imaging experiments at the Diamond Complex at Harwell to give new insight into this highly complex process.

The researcher would be part of a large, multidisciplinary team at the University of Sheffield, and integrated into the wider MAPP Hub and network, and supported by Rolls-Royce.
