The Illinois conference dealt with both traditional and newly developing topics in the area of phonon scattering. Maxime and Paris in 1972, at the University of Nottingham in 1975, at Brown University in 1979, and at the University of Stuttgart in 1983. The preceding confer ences were held at St. This volume contains the proceedings of the Fifth International Confer ence on Phonon Scattering in Condensed Matter held June 2-6, 1986 at the University of Illinois at Urbana-Champaign.
The Development of a 2D Ultrasonic Array Inspection for Single Crystal Turbine Blades should be an inspiration for those starting out on doctoral degrees as it shows the complete development cycle from basic science to industrial usage. The final site trial indicated an order of magnitude improvement over the best existing technique in the detectability of a certain type of root cracking. After extensive modeling, a suitable 2D array and deployment fixtures were manufactured and tested on in situ turbine blades in real engines. Another new method is described that enables volumetric images of an anisotropic material to be generated from 2D ultrasonic array data, based on measured crystallographic orientation. The book includes a description of a new method to determine crystallographic orientation from 2D ultrasonic array data.
The work – and the story told in the thesis – stretches all the way from the fundamentals of wave propagation in anisotropic material and ultrasonic array imaging through to device production and site trials. This thesis describes the development of a new technique to solve an important industrial inspection requirement for a high-value jet-engine component.
