Description
A modified quenching and deformation dilatometer (TA instruments DIL 805A/
D/T) is now in operation at the Heinz Maier-Leibnitz Zentrum (MLZ, Germany)
neutron center. It is customized for running neutron scattering measurements
during the temperature/deformation treatment of the sample, in particular
neutron diffraction (phase, texture, and lattice strain) and neutron small angle
scattering. The bulk length change of dilatometer specimens is successfully
combined with in situ neutron diffraction patterns for analyzing dynamic processes
in metallic materials. A detailed introduction to the unique dilatometer is
given and examples of recent experiments highlight the use of the added insight
provided by combining diffraction and dilatometry.
