Abstract Scope |
Laser powder bed fusion (L-PBF) offers a unique opportunity to manufacture complex components that are difficult to fabricate using traditional processes. However, due to complex thermal cycles during the layer-wise fabrication process, critical mechanical properties are expected to differ from the traditionally manufactured parts. To study this variation, this work reports the tensile and fatigue results obtained from miniature AlSi10Mg specimens tested on an in-house developed mechatronic system. During testing, the specimens are first subjected to a quasi-static tensile loading until rupture to understand the tensile properties – particularly the elastic modulus, the yield strength, and the ultimate tensile strength. The strain-controlled fatigue tests are then performed with a mean tensile strain to subject the specimens to a low cycle fatigue. The material hysteresis of the specimens is studied through the force-displacement curves at different stages during the fatigue life and estimates for total energy lost are computed. |
