Effect of Build Strategies on the Development of Residual Stresses in Laser Metal Deposited Ti-6Al-4V Aerospace Components

Abstract: Laser metal deposition (LMD) is a layer-by-layer additive manufacturing process used to produce near-net shaped components in the aerospace industry, with complex geometries that cannot be made via conventional manufacturing. A specific concern for LMD parts is the relation between process parameters with residual stress development and the effect on mechanical performance. Residual stresses are key factors causing tearing, mismatch of build layers and cracking in LMD components, due to complex thermal cycling from numerous melting, cooling and re-heating. Geometric height, materials properties and laser scanning path strategies affect the shape and magnitude of the residual stress profiles in LMD parts. This proposal is based on altering the build strategies, utilising different LMD scanning paths to characterise the effects on residual stress development in three Ti-6Al-4V T-Walls.
