Slow neutrons have been used in materials science for about 50 years. The principal reason for this is that neutrons are neutral particles and penetrate deep into materials. The principal croos-section of the slow neutron scattering is nuclear in origin. In particular, the neutron scattering cross-section for hydrogen is much greater than that for any other element and it also differs from that for deuterium. The neutron is a heavy particle so the changes in itsenergy may be easily measured by the change in its velocity. Both the de Broglie wavelength and the energy of thermal neutrons are matched to the length and energy scales in cindensed matter so not only the statics but also the dynamics of condensed matter may be studied in detail. The neutron possesses also a magnetic moment, which interacts with magnetic moments in solid allowing the details of microscopic magnetism to be examined, both electron and nuclear spins. Neutron scattering has played the principal role in understanding almost every area of modern physics and chemistry of materials. Here the selected applications of the neutron scattering technique in materials science are presented.
