Abstract
The structure and phase composition of samples of a Ti – 6Al – 4V alloy obtained using an EOSINT 280M laser printer are studied using scanning and transmission electron microscopy after cyclic three-point bending tests at room temperature. The features of the deformation process during bending of the samples are considered. It is shown that, in contrast to the cast alloy that fractures by a brittle mechanism, the Ti – 6Al – 4V alloy produced by laser 3D printing undergoes brittle-ductile fracture under the conditions of cyclic bending deformation, which is associated with formation of new pores in the deformed alloy.
