| Abstract Scope |
Metal additive manufacturing (AM) offers significant design flexibility, enabling the fabrication of complex geometries without the need for costly tooling. However, the qualification of metal AM parts remains time-consuming and requires extensive, expensive testing. This difficulty is primarily due to property variations across the part, which depend on geometry and process conditions, particularly the thermal history. In this study, micro-specimens (3 mm x 1 mm x 0.25 mm) are extracted from the gage section of standard samples, and their results are compared to standard samples reported in the literature. The study also examines how properties vary within the gage section as a consequence of thermal history. Micro-sample testing can identify critical regions within the component that may be overlooked by bulk testing. This approach provides a more comprehensive understanding of spatial property differences, thereby offering a stronger basis for assessing part performance. |
