- TITLE: COMPARATIVE NEUTRON DIFFRACTION STUDY OF RESIDUAL STRESSES, ARISING AFTER ELECTRON BEAM WELDING OF VARIOUS STEELS
- ABSTRACT: Electron beam welding is a technology in which residual stresses are formed as a result of temperature gradients. Neutron diffraction method allows the measurement of residual stresses in a high depth without destruction of the material. In this report, we present a comparative study of the residual stress distribution at electron beam welding carried out with approximately the same linear energy of three types of steel. Structural steel, stainless steel and pressure vessel steel, as well as a sample of welded pure copper and stainless steel were studied. Minimal residual stresses were obtained in the electron beam welded pressure vessel steel, which has the lowest coefficient of thermal expansion
