Development and application of neutron transmission imaging for strain mapping in aerospace applications
Science and Technology Facilities Council
ISIS Neutron and Muon Facility
Duration of project
2016 - 2019
This project, funded as an ISIS Facility Development Studentship, worked on the commissioning of the new IMAT beamline at the UK’s ISIS Neutron Facility.
The IMAT beamline was designed to combine neutron imaging, diffraction, and texture measurements in a single instrument, and the project delivered characterisation of the beamline performance, the development of novel analysis methods for neutron Bragg edge strain analysis, and exemplar applications of the new instrument to aerospace materials and structures.
The project delivered characterisation of the performance of the IMAT beamline for engineering application, and the neutron transmission method was applied for the study of manufacturing and repair technologies for aerospace aluminium alloys.
