Residual stress analysis in welds using materials science diffractometer STRESS-SPEC

The knowledge about the characteristics of stress and strain in welded assemblies are of vital importance for science, especially for the industry in the range of mechanical engineering. During the welding process a huge amount of heat in the area of the weldseam is responsible for changes in the microstructure of the material. Thereby, different stresses in magnitude and direction are developing. For Measurements an austenitic steel plate (AISI 316L) was used. This basic material is the most analysed material worldwide in science and therefore lots of datasets are available to compare the measuring results with the literature values. Only the shearing components of the stress tensor haven’t been analysed so far.

So the main part of this seminar is to exemplify and discuss the real existing stress tensor in the area of a weldseam. To reflect the advantages using neutron-diffraction for calculating the strain and stress components, other methods for determining the strain and stress components will be shown in the seminar. Also a short introduction of the experimental set-up STRESS-SPEC at the FRM II will be part of the presentation.
