Identifiability Limits in Ultrasonic Microstructure Characterisation: A Canonical and Stochastic Framework
Wei Yi Yeoh
Ultrasound for microstructure characterisation is increasingly studied and is often assessed through inversion performance. However, the framework is fundamentally constrained by t…

Investigation of the Influence of Macrozones in Titanium Alloys on the Propagation and Scattering of Ultrasound
Wei Yi Yeoh, Bo Lan, Michael J. S. Lowe
The presence of macrozones (or micro-textured regions) in Ti-6Al-4V (Ti64) was shown to be a potential cause to the onset of cold dwell fatigue which reduces fatigue life significa…
