Neutron scattering, a powerful tool in material science considering superalloys as an example
Abstract
The characterization of the microstructure in superalloys is predominantly carried out with microscopic methods. Due to the low penetration of X-rays, electrons or light, the samples have to be very thin by using transmission methods and the investigation is limited to the surface. Neutrons enable to enlarge the investigated sample volume, both the crosssection, due to the large size of neutron beams, and the thickness up to a few millimeters, because of the favourable penetration depth. This article presents various examples in the field of superalloys, as in situ measurements at high temperatures, the detection of rare detrimental single plates randomly distributed in the sample, or the determination of lattice constants. This demonstrates how worthwhile it is using the non-destructive tools of small-angle neutron scattering and neutron diffraction to solve challenges arising in material science.
