In-situ scattering and diffraction measurements using synchrotron and neutron beam lines have become a viable tool to look at the non-equilibrium processing of advanced materials. This volume presents the subject from the theoretical and experimental standpoint, in order to provide a closer insight into the different synchrotron and neutron diffraction techniques as well as innovative microscopy techniques.
