| Abstract Scope |
Nickel-aluminum bronze (NAB) alloys are commonly used for marine applications such as propellers and valves. Recent interest has shifted to replacing conventionally cast NAB components with those fabricated using large-scale, wire-arc additive manufacturing (WAAM) processes. However, residual stresses and part-level distortion in as-built parts can contribute to build failures and reduced performance in components produced by additive manufacturing (AM) techniques, which hinders process qualification and part certification due to reduced performance. Implementation of higher interpass temperatures is being investigated as a mitigating technique to reduce distortion and residual stresses. This study used commercial AM simulation tools to analyze how differing interpass temperatures can influence the as-built residual stresses in a WAAM-built NAB part. The predicted results were validated using the contour method to quantify the amount of residual stress in the selected component. |
