“…Gripenberg at al. [21] used three different methods to study the residual stress profile in very thick (10 mm) austenitic steel welding clad on a ferritic steel substrate. They detected a clear change from tensile to compressive residual stresses when proceeding from the clad to the base material.…”

Residual stress analysis in Co-based laser clad layers by laboratory X-rays and synchrotron diffraction techniques de Oliveira, U.; Ocelik, Vaclav; De Hosson, J.T.M.

AbstractThick Co-based coatings were prepared by laser cladding technique on C45 steel substrates with different geometries. Microstructural observations were realized using optical, scanning electron and orientation imaging microscopy. The residual strain state on the surface of a clad layer was determined by the sin 2 Ψ-technique using laboratory X-rays. The diffraction of synchrotron radiation in θ-2θ was used to acquire information from the bulk of the materials. Internal stress was characterized through the depth and width of the coatings. Elastic moduli required for stress state calculation were measured by the nanoindentation technique and also estimated from moduli of γ-Co single crystal. A misorientation between principal strain direction and cladding direction was observed on the surface of Stellite 20 coating. The stress profiles inside clad layers reveal the influence of scanning speed, clad layer shape, laser tracks overlap and stress release component due to crosssectioning. The strong texture inside the coatings affects diffraction conditions, the precision of the measurements and also ability to collect experimental data.
