Abstract

The dependence of residual stresses in martensitic-austenitic age-hardenable steels on a different technological treatment (welding by electron beam, postweld heat treatment) were investigated using a neutron diffraction. Experiments were performed in NPI Řež on a high-resolution diffractometer equipped with cylindrically bent perfect crystals. The resolution of the instrument (Δd/d ≈ 10-4; d-lattice spacing) enabled us to investigate plastic strains in weld joints.
