Abstract Scope |
The fatigue behavior of Additive Manufacturing (AM) Ti-6Al-4V has been widely investigated under axial loading, with limited analysis of its performance under bending conditions. Internal defects in AM parts can detrimentally affect the integrity of 3D-printed specimens, impacting their fatigue performance. Researchers have previously implemented the Hot Isostatic Pressure (HIP) post-processing method to address the presence of defects. This study explores the fatigue life of L-PBF Ti-6Al-4V after three HIP treatments: standard, low temperature/high pressure (LTHP), and super beta HIP, alongside annealed heat treatment. Optical techniques were utilized to assess microstructure, while tensile and hardness testing examined mechanical properties. Fracture morphologies and stress-life (S-N) curves were analyzed to understand fatigue behavior. Initial findings indicate that specific HIP post-processing can enhance the fatigue performance of Ti-6Al-4V under 4-point bending. |
