Abstract Scope |
Additive manufacturing (AM) can be used to design complex shape components, which have application in power plants for repairing or component processing. However, it often introduces complex thermal cycles during beam melting causing undesired microstructure-property relationships. Therefore, the process-structure-property correlations are challenging to model, and thus impede the materials and process design for power plant construction applications. Fortunately, the AM technique itself sometimes enables us to accelerate alloy design by acting as a high-throughput design tool. In this talk, we will review some new opportunities regarding AM of structural materials that can potentially be used for power plants. We will highlight some case studies on alloy development for AM through graded alloy processed by directed energy deposition with both powder and wire-based techniques. Through case studies, such as Haynes 282 and P91/740H graded alloy AM, we will identify both challenges and design pathways. |
