 Abstract:
Anisotropy of stress-strain behavior, fracture toughness, and fatigue crack growth rate was studied for Ti6Al4V deposited by cold spray using nitrogen. For that, flat deposits were tested with stress acting in the in-plane directions and thick tubular deposits were used to test out-of-plane (radial) stress directions. For all three test types, unified bending specimens of small size were used. It was shown that for the in-plane stress, the deposits can be considered isotropic, whereas the out-of-plane stress led to significantly lower values of the measured properties. The obtained results were explained with the help of fractography and microstructural analysis and attributed to the particle decohesion mode.
