ULTRASONIC TIME OF FLIGHT DIFFRACTION - Dacon

The Time-of-Flight Diffraction (TOFD) technique is rapidly gaining importance as a stand-alone inspection technique. TOFD is an advanced ultrasonic inspection technique that fulfils a need for reliable inspections. It is a powerful technique because it can simultaneously detect and size defects. Time of

Texture Investigations by Neutron Time-of-Flight Diffraction

NEUTRONTIME-OF-FLIGHT DIFFRACTION 311 For the most of isotopes the incoherent scattering is of low intensity. However, for hydrogen it is extremely predominant. Therefore, neutron diffraction measurements including texture studies at materials containing hydrogen like polymers are very complicated. These difficulties can be overcome using deuterated specimens. Magnetic diffraction …
