The main aim of this project is to measure the residual stress profile for induction hardened steel samples (steel grade 42CrMo4) and verify the existence of a tensile stress peak below the hardened surface observed in modeling. The results will be compared with the simulated results. The measurements with neutron diffraction will also be compared to measurements with common XRD techniques. Only with neutron diffraction it would be possible to measure the residual stresses non-destructively without removal of material. This is a resubmission. The reviewer's comments were to validate the thermal and constitutive model, which is indeed exactly the aim of this proposal.
