Mechanical properties of high-performance AM materials

• Due to the inherent nature of the processes used for additive manufacturing (AM), the AM materials often display uniquemicrostructures that differ from their conventionallymanufactured counterparts. This will also influence the mechanical properties of these alloys. This chapter gives anoverview of the impact of the AM-specific features typicallyfound in the microstructure of high-performance materials. This includes the strengthening effects from the cell and grainstructures in powder bed fused materials. The origin of theanisotropic behaviors and fracture mechanisms present in thematerials, especially at elevated temperatures are reviewed. Finally, the influence of typical surface conditions, internal defects, and microstructure on fatigue behavior will be discussed.
