Residual stresses in laser direct metal deposited Waspaloy

▶ Neutron diffraction and the contour method show good agreement. ▶ Tensile stresses found parallel to the surfaces. ▶ Compressive stresses within the bulk of the structures. ▶ Residual stress weakly dependent on the laser pulse parameters. ▶ Maximum tensile residual stress unaffected across range of pulse parameters used.
