| Abstract Scope |
Additively manufactured (AM) metallic components have highly anisotropic microstructures spanning multiple length scales. The relationship between microstructure and mechanical properties of printed structures is complicated by the introduction of additional design parameters, such as build orientation and geometric variations. This study was undertaken to decouple the contribution of texture and geometry on the mechanical response of thin-walled IN625 T-elements fabricated by laser powder bed fusion. The T-elements were printed at either 40° or 90° inclinations from the build plate resulting in a 10% difference in the ligament widths. T-elements underwent a standard stress-relief heat treatment and subsets of each build orientation were subsequently homogenized at 1150°C for 90 minutes. Milli-scale tests indicate that the 90° T-elements are stiffer in both heat-treated states. However, a higher fraction of <111>- and <110>-oriented grains along the loading direction in the stress-relieved 40° T-elements suggests a stiffer response than the 90° counterpart. |
