| Abstract Scope |
The phase field model is a powerful computational technique that can be used to simulate the evolution of microstructures in a variety of materials and processes. During additive manufacturing (AM), the rapid solidification of metallic materials can result in significant internal stresses. Material properties such as strength, ductility, and toughness can be profoundly affected by these stresses. In this study, phase field modeling is used to investigate how microstructural evolution impacts the mechanical properties of AM metals during rapid solidification. Simulations provide an opportunity to observe how dislocation substructures and solute segregation interact during the process. These microstructural factors play a crucial role in determining the overall performance of the material. In our study, we employ a generalized modeling approach to identify the key factors contributing to stress development and their subsequent impact on material performance, ultimately providing insight into the optimization of the mechanical behavior of AM components. |
