| Abstract Scope |
This presentation investigates the mechanical properties of additively manufactured lattice structures made of Ti-6Al-4V and Ti-5Al-5V-5Mo-3Cr alloys with different topologies. The focus is on how the local response of the strut scales up to the macroscopic behavior and failure mechanisms. Ti-6Al-4V, with its alpha-phase-dominated microstructure, exhibits a higher strength-to-elongation ratio, whereas Ti-5Al-5V-5Mo-3Cr, characterized by a dominant beta-phase microstructure, demonstrates improved ductility and fracture toughness. These microstructural differences result in distinct deformation mechanisms and mechanical behavior, which this presentation discusses in detail. |
