Residual stresses around welds in nickel-based superalloys

Abstract:

Welding of nickel-based superalloys is employed in the manufacture of many important components of the jet engine, such as combustor casings, compressor disc assemblies, etc. Welds induce microstructural modification in the weld seam and the heat affected zone (HAZ) which generally reduce the fatigue resistance compared to that of the parent metal. Welds also generate significant residual stresses, both locally due to combination of solidification shrinkage and high temperature plastic deform...
