Abstract Scope |
Powder-bed fusion additive manufacturing of high-temperature alloys plays a critical role in enabling the U.S. to meet clean energy goals and maintain a strong national security posture. It is well-known that additive processes can be susceptible to various types of manufacturing/material defects that occur during processing, especially during the production of complex geometries. Furthermore, additive processed materials often have unique microstructures when compared to cast or wrought materials that must be accounted for when establishing microstructure-property relationships and qualifying materials and components. To this end, we develop a full-field crystal plasticity surrogate model and train it on simulations containing explicit defects to rapidly predict the influence of the defect on the material’s mechanical performance. In this presentation, we present the model architecture and assess its performance for a recently developed Molybdenum alloy processed via electron beam melting. |
