| Abstract Scope |
There is a need to simulate the linkage between processing parameters and microstructure in the laser powder bed fusion metals additive manufacturing process. Additionally, it is important that these models be efficient to fit well into simulation pipelines to predict the process, structure, and properties relationship without creating bottlenecks. Presented here is a low-cost model that simultaneously simulates entire laser passes. This “Pass Scale Model” utilizes <100> type preferred growth to inform both the morphology of the 3D microstructure and include texture information in the output. These synthetic microstructures extend hundreds of microns in each direction with model run times of a few hours. Of note is the introduction of a modified Rosenthal thermal model to calculate the shape of non-conduction mode melt pools. The model method and validation against experimental results for both grain morphology and texture via the Wasserstein Distance will be shown. |
