Abstract Scope |
This study presents an experimental investigation into the effect of the Area Printing® additive manufacturing (AM) process on SS316L microstructure. Specifically, grain size, grain morphology, and texture were quantified as a function of position within a printed part. This data was used to validate a reduced order microstructure model built to simulate competitive grain growth in a relatively large Area Printed volume of SS316L. The model uses the Discrete Dendrite Dynamics (DDD) framework, which takes advantage of a computationally efficient Lagrangian approach of tracking dendrite tips during dendritic, epitaxial solidification during AM processes. The goal is to leverage this model to achieve controlled grain growth through AM, and preliminary results show that optimized AM parameters and part geometries can achieve quasi-single crystalline growth. This research offers significant insights into optimizing AM processes for controlled crystal growth, contributing to developing superior materials for industrial applications. |
