| Abstract Scope |
In additive manufacturing, tungsten is recognized for its exceptional high-temperature resistance, making it suitable for extreme conditions. However, its brittleness and susceptibility to thermal cracking pose significant challenges. This study examines the microstructural evolution of tungsten processed through an innovative technique: rolling in laser powder bed fusion additive manufacturing. By combining advanced simulations with empirical research, we focus on understanding plastic deformation and microstructural transformations, particularly grain size dynamics, boundary evolution, and phase distribution. The integration of simulation and experimental data allows us to identify key mechanisms driving microstructural changes during the rolling process, enhancing our understanding of tungsten's behavior in additive manufacturing. These insights not only expand theoretical knowledge but also offer practical strategies for improving the mechanical properties of tungsten components. Our approach provides a robust framework for developing durable materials for challenging environments, optimizing additive manufacturing techniques, and broadening the application of tungsten in demanding sectors. |
