Abstract
The effect of model porosity (30; 40; 50, and 60%) on the mechanical and electrical properties, as well as the fracture micromechanism of samples produced by 3D printing from Ti–6Al–4V ELI powder, was investigated with the aim of developing a technology for manufacturing porous anode substrates of the lightweight solid oxide fuel cells. After annealing in argon, the material of the samples exhibits a martensitic structure typical of the Ti–6Al–4V alloy. At a porosity of 60%, the tensile and flexural strengths are 169 and 289 MPa, respectively, under a mixed fracture mode involving dimpled and intergranular mechanisms. The electrical conductivity is 2105 S/m, which meets the requirements for materials used in fuel cell components.
