| Abstract Scope |
Large scale metal additive manufacturing provides a pathway to solve the supply chain issues related to high performance metals and alloys processed by traditional manufacturing routes like casting and forgings. Due to the inherent nature of layer-by-layer deposition, it is also possible to transition from one alloy to impart site specific properties for wide range of industrial applications. However, the qualification of these parts remains as a challenge due to familiar issues including defects, residual stress, distortion, heterogeneous microstructure, and properties. In this talk, approaches to meet these challenges based on existing welding literature will be outlined with case studies to produce stamping dies. In this case study, dissimilar metal joint between mild steel and martensitic steel was produced and the interface characteristics were analyzed using thermomechanical simulator. Based on these data, future directions to develop qualify materials as you deposit by coupling modeling and in-situ sensing will be outlined. |
