Abstract:
Laser Powder Bed Fusion (LPBF) enables the production of Ti-6Al-4V alloys with porous structures beneficial for biomedical applications due to reduced elastic modules and enhanced bone integration. This study examines the effect of Hot Isostatic Pressing (HIP) on the microstructure and mechanical properties of Diamond and Gyroid porous structures fabricated by LPBF. Solid tensile specimens served as reference materials. HIP significantly reduced porosity decreased ultimate tensile strength and hardness, but markedly increased ductility (from 6% to 17%). Compressive strengths reached approximately 100 MPa (Diamond) and 240 MPa (Gyroid), with HIP causing only a slight increase in strain. However, HIP notably improved bending performance, raising Gyroid flexural strength from 280 MPa (as-printed) to 340 MPa (post-HIP).
