Effect of Substrate Alloy Type on the Microstructure of the Substrate and Deposited Material Interface in Aluminium Wire + Arc Additive Manufacturing
TL;DR: In this article, the effect of substrate type on the interface microstructure in an aluminium part was investigated, and the results showed that the deposited material hardness is always lower than the substrate hardness, but this difference can be minimized by heat treatment and even eliminated when the substrate and wire are made of the same alloy.
