Abstract

Structure of the Ti–6Al–4V alloy samples after cyclic three-point bending was studied by a scanning electron microscopy. Samples with the different build geometry were manufactured by laser powder bed fusion method (L-PBF) using 3D laser printer. The valuation of degree of the structure degradation in L‑PBF Ti–6Al–4V alloy samples after three-point bending fatigue test at room temperature was done. It was found that the values of maximum strength loading and build geometry of the L-PBF sample are associated with the nature of its fracture under cyclic bend deformation.
