Micro stresses in welded high-strength stainless steels

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 neutron diffraction. Experiments were performed in NPI Rez on a high-resolution diffractometer equipped with cylindrically bent perfect crystals. The resolution of the instrument ({Delta}d/d {approx} 10{sup {minus}4}; d-lattice spacing) enabled the authors to investigate plastic strains in weld joints.
