Influence of heat cycling conditions in the additive manufacturing of stainless steel and al-si alloy raw parts on their microstructure

Abstract

The microstructure of samples of austenitic stainless steel and Al-Si alloy, obtained by the wire based additive method under various conditions was investigated. The effect of the beam current, the deposition intervals and the electron beam post-processing on the microstructure is shown.
