Dr. Thomas Gnäupel-Herold’s research focuses on residual stresses in materials using neutron diffraction. Residual stresses occur as the result of inhomogeneous distortions in almost all materials. These distortions are caused by mechanical, thermal or chemical treatments that affect a specimen (the ‘part’) inhomogenously, e.g. only at the surface. They can be measured using diffraction by probing the distance between lattice planes in crystalline materials. By comparing the lattice distortions
