TL;DR: In this article, the effects of laser shock peening on the hot corrosion behavior of the selective laser melted (SLMed) Ti6Al4V titanium alloy were investigated and the results indicated that the SLMed specimen exhibited a significantly lower hot corrosion resistance in comparison to the SLM-LSPed specimen.

TL;DR: In this article, the microstructure evolution during LSP was investigated via electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) observations, and the micro-hardness distributions on cross-sections and subsurface residual stress states as functions of the laser energy were also determined.

TL;DR: In this paper, a method for producing a metallic article with a metallic substrate, at least one metallic layer sprayed onto a laser-shatter peened surface area of the substrate, and a region having deep compressive residual stresses imparted by laser-shock peening extending into the substrate from the laser-peened surface was described.
Abstract: A metallic article and method for producing such an article, having a metallic substrate, at least one metallic layer sprayed onto a laser shock peened surface area of the substrate, and a region having deep compressive residual stresses imparted by laser shock peening extending into the substrate from the laser shock peened surface. The metallic substrate and or layer may be made from an alloy such as a Cobalt or a Nickel based superalloy. The substrate may be made from Nickel Base forgings or Titanium base forgings. An exemplary embodiment of the present invention is a gas turbine engine rotor component such a disk and, more particularly, a turbine disk suitable for use in a hot section of a gas turbine engine. The invention may be used for new or refurbished parts to restore dimensions of the component and, in particular, radial dimensions.
