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

Roland Logé, Reza Esmaeilzadeh, Claire Navarre, Shieren Sumarli

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 specimen i ...
