Abstract
Peak broadening of neutron diffraction was studied at various neutron wavelengths (1.24–2.61 Å). As the neutron beam path through a specimen increased, significant peak broadening was observed in ferritic steel, but not in austenitic steel. The peak broadening was reduced under a magnetic field applied perpendicular to the beam direction. Small-angle neutron scattering results showed significant reduction in scattering intensities under a magnetic field of 1.2 T. It is suggested that the peak broadening can be attributed to multiple small-angle neutron scattering by magnetic domains. Thus, a sufficiently strong magnetic field could enhance the deep penetration capability of neutron diffraction by reducing the peak broadening.
