| Abstract Scope |
Cold spray is a solid-state particle deposition technology that yields low porosity and residual stresses in the deposit, relative to thermal spray processes. However, as cold spray moves into the manufacturing of near-net-shape parts, it is becoming apparent that residual stresses play a significant role. Observed failure modes include the separation of the deposited part from the substrate and the development of circumferential and/or axial cracks in the parts. The shape, size, and duration of the deposition appear to influence these failure modes. Other culprits should include the coefficient of thermal expansion mismatch and thermomechanical effects. In this presentation, an overview of the residual stresses in additively manufactured parts will be given. Analytical and numerical methods will be employed to predict and explain the observed failure modes. |
