Introduction

Residual stress is one of the most common causes of catastrophic and unexpected failures in engineering components. Today, engineers are developing tools and strategies for managing detrimental residual stresses and for introducing beneficial ones across component scales ranging from microelectronics through to aero-engine assemblies.

This workshop is aimed at anyone who would like to know more about measuring residual stress using diffraction techniques.

It is suitable for beginners, as well as more experienced practitioners. The workshop aims to cover all diffraction methods, neutron, synchrotron and laboratory X-ray and consequently, will also be of interest to those who already have experience in one field and would like to extend their knowledge into others. We will also cover sample preparation techniques as well as layer removal by electro polishing.

There will be an opportunity to make a measurement using two of Manchester's "state of the art" stress diffractometers. You can bring a sample is you wish; please let us know in advance.

This workshop will be run by Judith Shackleton, Dr Michael Preuss and Dr Jo Kelleher who are members of 'The Residual Stress and Damage Characterisation Unit' at The University of Manchester, School of Materials which is a centre of expertise for diffraction and many other methods.
