| Abstract Scope |
Additive manufacturing unlocks novel opportunities in terms of alloy and microstructure design, through on-the-fly alloying and gradient deposition. Here, we present a workflow that allows for high-throughput synthesis of functionally graded alloys using direct energy deposition and process monitoring. Strategic extraction of tensile specimens enables to test all compositions within the gradient in iso-stress conditions. Using multi-modal datasets combining EDS, EBSD and high resolution digital image correlation, all collected automatically in the SEM via python scripting, we measure strain localization and identify the deformation mechanisms as a function of the local composition and microstructure. These large and multi-modal datasets enable to predict complex mechanical properties such as fatigue strength. This method will be compared against conventional bulk mechanical testing. |
