IDLA Phase discrimination using resonant ultrasound spectroscopy

This PhD research opportunity focuses on using resonant ultrasound spectroscopy to characterize the microstructure of steels. The microstructures of steels are sensitive to small variations in composition and processing conditions, which can lead to property variability. This research aims to address the challenge of discriminating microstructural constituents through acoustic methods that exploit the different elastic behaviour of phases present. The project will utilize resonant ultrasound spectroscopy to determine the elastic response of selected steels in varying microstructural conditions and correlate results with microstructures obtained using microscopy methods. Initial work will use untextured samples to avoid complications from acoustic anisotropy, before extending to samples with crystallographic texture and monitoring phase transformation in-situ during heat treatments. The successful applicant will receive training in all computational and experimental methods required for the project, although relevant previous experience would be advantageous.
