Mechanical and microstructual investigation of 3D-printed Alloy 625

Abstract

Additive manufacturing is in the wind and shows great promise as a manufacturing technique. In this thesis the properties of the additive manufactured EOS alloy 625 is investigated. Tensile, CharpyV, Vickers, and pitting corrosion test have been performed to investigate the material properties, and it has been inspected in the SEM and with light microscopy. The material properties were found to be within the range of the EOS specifications. Many interesting additional properties and details were found, as explained in the discussion and conclusion.
