Neutron Bragg edge imaging for strain characterization in powder bed additive manufacturing environments

Autor: Shieren Sumarli, Efthymios Polatidis, Florencia Malamud, Matteo Busi, Claire Navarre, Reza Esmaeilzadeh, Roland Logé, Markus Strobl

Publikováno v: Journal of Materials Research and Technology, Vol 21, Iss , Pp 4428-4438 (2022)

Spatially resolved studies of crystalline structures, e.g. lattice spacings, are enabled by recording the transmitted spectra in neutron Bragg edge imaging. The recorded signals are, however, a result of through-thickness averaging of the probed spec
