High susceptibility of 3D-printed Ti-6Al-4V alloy to hydrogen trapping and embrittlement

Popis výsledku v původním jazyce

Today, 3D-printed titanium components become increasingly utilized in various fields thanks to the great shape freedom that 3D printing offers, especially in aerospace, automotive, power industry, or in the fabrication of progressive medical implants. However, in this paper, we demonstrate a high susceptibility of 3D-printed Ti-6Al-4V alloy to hydrogen trapping and embrittlement supported by its specific microstructure. 3D-printed (Selective Laser Melted) and wrought Ti-6Al-4V alloys were electrochemically hydrogenated under the same parameters. In comparison to conventionally prepared wrought alloy, the content of hydrogen trapped in the 3D-printed alloy after electrochemical charging was twofold (5458 ppm vs 2857 ppm, respectively). Heat treatment slightly decreased the susceptibility to hydrogen trapping. Even though, a complete embrittlement was observed for all 3D-printed samples.
