Abstract Scope |
Additive manufacturing techniques often introduce unique thermal history due to cyclic heating and cooling during beam melting. Therefore, the process-structure-property correlations are unique and challenging to model, which impedes the materials design and process optimization. Fortunately, the additive manufacturing 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 alloy design for additive manufacturing. We will highlight some case studies on alloy development for additive manufacturing through graded alloy processed by directed energy deposition with both powder and wire-based techniques. Through the discussion on 316L/HSLA steel, 316L/Inconel718, Haynes 282, and P91/740H graded alloy additive manufacturing, we will further evaluate the technical challenges associated with heat treatment optimization, which is essential for additive manufacturing alloys with precipitation hardening. |
