| Abstract Scope |
An emerging approach to address material heterogeneities in additively manufactured materials is the combination of deformation and deposition processes. While extensive data exists regarding the flow properties of traditional alloy systems, such data is limited for additively manufactured materials. To address this knowledge gap, work is exploring the use of methods to accelerate the quantification of material flow behavior. Material samples under evaluation include common right circular cylinders, but also a double cone geometry to introduce a range of strain values within a single experimental compression test. Further, flow and recrystallization behavior has been captured across a range operating temperatures using a Gleeble 1500D thermo-mechanical simulator. Experimental results are coupled with computational models to yield material insights, but to also develop design and process predictions necessary for practical application. Results will be presented from testing 316L in both wrought and additive forms. |
