THE STUDY OF AMORPHOUS AND NANOCRYSTALLINE MATERIALS BY NEUTRON-SCATTERING METHODS

It is well known that neutron diffraction, inelastic scattering, quasi -elastic scattering, small-angle scattering and reflectometry have all been applied in the past to study the static and dynamic structures o f amorphous, microcrystalline and nanocrystalline materials. More rece ntly the reactions in new forms of amorphous materials have been studi ed in real-time in-situ neutron experiments. Some examples will be giv en in this paper of how neutron scattering can contribute to the evolu tion of better materials such as metallic alloy glasses, metallic thin -film multilayers and amorphous mechanically alloyed samples for techn ological applications.
