Microstructure and residual stress analysis: Research on matter with brilliant light sources & Neutrons for research on condensed matter
One advantageous feature of neutrons, compared to X-rays, is their large penetration depth within the bulk of a material. Neutrons are ideally suited to non-destructive testing of crystallographic properties deep inside simple geometric samples as well as in complex industrial components. As part of a complementary suite of X-ray, synchrotron and neutron instruments within one department we operate the angular-dispersive neutron diffractometer E3 at the BER II research reactor to study material science phenomena.
The E3 is dedicated to measurements of residual stresses in engineering materials by determining the local lattice strain. The impact of applied loads on material properties can be investigated by tension, compression and torsion load frames. In-situ / ex-situ experiments with high-temperature furnaces and cryostats, for example, are allocatable in conjunction with our in-house sample environment. Further applications on E3 are available by analyzing microstructure and magnetic phase information, texture, grain sizes and mosaicity in polycrystalline samples, composites, single crystals and foams respectively.
In-house research & instrument development for user service
As part of our own research and rising to the challenge of a growing demand from science and industry for neutron beamtime, we continuously develop methods and upgrade our instrument to extend the range of applications on E3, make measurements faster and more precise. In order to use beamtime efficiently, the reduction of set-up times of measurements is as important. We provide full user service to our national and international users by supporting the preparation, execution and analysis of an experiment including detailed data post-processing by custom-developed software tools. We take part in round robin standardization activities, bridge gaps to surface zone investigations.
