| Abstract Scope |
Additive manufacturing technologies enable rapid production of parts with complex geometry which cannot be shaped in other conventional methods. The AM-fabricated parts experience rapid solidification and high cooling rates; this leads to formation of typical microstructure and directly affects the intrinsic properties of the printed part and on its environmental-assisted degradation. In this research, the environmental degradation by means of corrosion and hydrogen embrittlement of structural materials (Ti and SS) produced by AM technologies will be presented.
Hydrogen presence is unavoidable in most manufacturing processes and services. Hydrogen can significantly deteriorate mechanical properties and lead to unexpected failure. The hydrogen interaction with the material is strongly dependent on the type of the metal, microstructure, the amount of adsorbed hydrogen, and its location in the material. The aim of the research is to provide detail information about the environmental degradation of AM-produced structural materials in aggressive service conditions for further application. |
