Integrated substructure analysis in polycrystals is often based on the interpretation of physical diffraction-line broadening. In the present work the case of high-resolution neutron diffraction by means of RTOF is considered in comparison with the angular-dispersive neutron diffractometry. First experimental results indicate that RTOF can successfully be used for the determination of physical line-broadening.

Low-energy neutron transmission diffraction has been successfully demonstrated to be a powerful experimental method to investigate changes in crystal structure development down to the millisecond range. Bragg edge diffraction measurements thus can be the basis for future experiments like strain radiography, determination of the strain-rate dependent elastic properties of engineering materials, temporal development of phase changes, structural properties of materials under extreme environmental conditions like high pressure or temperature states. At high instantaneous neutron bursts current-mode detection can be used, which enables both transient and stroboscopic measurements. Progress has been made in rapid data acquisition and analysis as well as temperature measurement by resonance doping.
