Abstract

In general, neutrons offer the advantage to be weakly absorbed by materials. Consequently neutron scattering is a very efficient tool to probe deeply inside the materials in a non destructive manner. Time resolved neutron scattering is thus widely used by different scientific communities: materials science, physics, chemistry… It is now possible to perform neutron diffraction in situ, in complex environments: electrochemical reaction ce ls, pressure cells… In situ neutron diffraction has been widely developed on high neutron flux sources such as the Institut Laue Langevin (Grenoble). Neutron scattering is a very useful technique for time resolved reaction processes inside materials. The experimental set-up needed for such type of experiments is briefly presented. Thereafter, examples of recent applications of neutron diffraction are described to illustrate the possible use of thermodiffractometry, in situ and/or time resolved to investigate phase transitions of chemical processes. The examples are taken in different scientific fields: metalurgy, electrochemistry, magnetism, solid state chemistry, archeometry..
