Neutron diffraction techniques have become an established technique in engineering
material science. Neutron small angle scattering and neutron diffraction are valuable
tools for material characterization and the development of new materials. In addition
neutron diffraction, in particular residual stress analyses and neutron tomography
reveal unique information due to allowing a non-destructive testing of components.
Neutron diffraction and tomography thus can play an important role for the optimization
of manufacturing processes.
The availability of synchrotron radiation has strongly expanded the spectrum of techniques
available for investigating material microstructures, their development and also
their degradation under thermal and mechanical loading. A multitude of different
approaches e.g. using diffraction methods for the analyses of residual stresses give
complementary information to those obtained by neutron diffraction. The high brilliance
at modern synchrotron radiation sources further provides new insight in-situ
into very localized and time-dependent phenomena, e.g. into the growth of individual
crystallites in a polycrystalline material and the nucleation and into the development
of voids in materials subjected to loading at high temperatures.
In addition to several examples showing the impact of investigations using neutrons
and synchrotron radiation on material and component development in engineering
material science, an example will be presented which highlights the complementarity
of the three probes (neutrons, synchrotron radiation and ions) in an investigation of
an ancient nanomaterial.
