Book Description
Measurement of Residual and Applied Stress Using Neutron Diffraction
Author: M.T. Hutchings
Publisher: Springer Science & Business Media
ISBN: 9401127972
Category : Technology & Engineering
Languages : en
Pages : 568
Book Description
The accurate, absolute, and non-destructive measurement of residual stress fields within metallic, ceramic, and composite engineering components has been one of the major problems facing engineers for many years, and so the extension of X-ray methods to the use of neutrons represents a major advance. The technique utilizes the unique penetrating power of the neutron into most engineering materials, combined with the sensitivity of diffraction, to measure the separation of lattice planes within grains of polycrystalline engineering materials, thus providing an internal strain gauge. The strain is then converted to stress using calibrated elastic constants. It was just over ten years ago that the initial neutron diffraction measurements of residual stress were carried out, and during the ensuing decade measurements have commenced at most steady state reactors and pulsed sources around the world. So swift has been the development of the field that, in addition to fundamental scientific studies, commercial measurements have been made on industrial components for several years now. The use of neutrons is ideally suited to the determination of triaxial macrostress tensors, macrostress gradients, and microstresses in composites and multiphase alloys as well as deformed, plastically anisotropic metals and alloys. To date, it has been used to investigate welded and heat-treated industrial components, to characterize composites, to study the response of material under applied loads, to calibrate more portable methods such as ultrasonics, and to verify computer modelling calculations of residual and applied stress.

Residual Stresses and Thermal Fatigue in Metal Matrix Composites
Author: Michael Schöbel
Publisher: Sudwestdeutscher Verlag Fur Hochschulschriften AG
ISBN: 9783838128993
Category :
Languages : en
Pages : 148
Book Description
Metal matrix composites are developed as heat sink materials with superior thermal properties. Future applications like power electronics or fusion reactors require new solutions on thermal management. In this work several composite types with fiber and particle reinforcements were investigated under simulated operation conditions, concerning their internal stresses and thermal fatigue damage. New non-destructive methods such as neutron/synchrotron diffraction and synchrotron tomography were combined for in situ experiments. The phase sensitive study of elastic as well as plastic deformation processes on the microscopic scale allowed conclusions on reinforcement architectures, their types and effects on thermal fatigue damage in composites. A comparison of neutron with synchrotron radiation was given by the example of diffraction and its experimental capabilities for heterogeneous materials.
