| Abstract Scope |
Microstructure evolution during AM is governed by processes on time and length scales that encompass many orders of magnitude. Melting and evaporation processes have to be described on a nanosecond scale whereas the whole building process takes many hours. Many effects during AM, such as binding faults, surface roughness or epitaxial grain growth from the powder bed, can only be understood by taking into account individual powder particles, i.e. on the microscale, whereas the component size is in the range of centimeter. This contribution discusses the state-of-the-art of AM microstructure prediction and reveals gaps to be filled in the future. |
