INDUSTRIAL APPLICATIONS OF THERMAL NEUTRON SCATTERING

It is now over twenty years since Harwell Laboratory pioneered the industrial use of neutron scattering. This review describes why the methods developed are now becoming accepted worldwide as among the most important techniques in non destructive testing. The ability to penetrate several centimeters of most materials is the properly that gives neutron beams a unique advantage. The principal experimental techniques of industrial neutron scattering: High Resolution Neutron Diffraction (HRPD), Small Angle Neutron Scattering (SANS), Inelastic Scattering and Neutron Radiography are described. Some of the principal applications are then discussed: ∗The measurement of residual stress in components. ∗The microstructure of metals and porous media. ∗The texture of materials. ∗In situ studies of chemical reactions and catalysis. ∗The flow of hydrogenous liquids inside metallic components. The review ends with an account of Harwell's experience in performing contract research for industry. Industrial customers generally require a complete service from initial discussions to a final report.
