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.

激光3D打印制备Ti - 6Al - 4V合金的组织和相组成及循环弯曲试验

采用EOSINT 280M激光打印机对Ti - 6Al - 4V合金试样进行了室温三点循环弯曲实验，并用扫描电镜和透射电镜研究了试样的组织和相组成。考虑了试样弯曲变形过程的特点。结果表明：与铸态合金脆性断裂不同，激光3D打印制备的Ti - 6Al - 4V合金在循环弯曲变形条件下发生脆性-韧性断裂，变形合金中形成新的孔隙；
