Abstract Scope |
The alloy design cycle for additive manufacturing requires significant time for characterization, both to optimize process parameters for minimization of defects, and to understand the alloy microstructure and properties. Reducing time required for these characterization tasks is an opportunity to accelerate alloy development for AM, rapidly optimize process conditions, increase system utilization, and improve part quality. This presentation will outline an approach for efficiently and rapidly selecting and characterizing laser powder bed fusion process parameters for a new Al alloy using x-ray computed tomography, optical microscopy, hardness testing, and other techniques. The advantages and disadvantages of possible characterization approaches will be discussed, and recommended approaches for rapid parameter development will be presented. Finally, the outlook for alloy and process development utilizing new advanced characterization techniques and their impact on the AM community and broader industrial interests will be considered. |
