“…Post-processing heat treatment process is not ideal for the mitigation of micropores in additively manufactured Al alloys. Many studies have shown that secondary pores are formed after heat treatment owing to factors such as the dissolution of some eutectic phases and the Ostwald ripening effects [104]. The anneal heat treatment did not significantly influence the porosity level in the L-PBF AlSi10Mg parts.…”

The application of Metal Additive Manufacturing (MAM) in the aerospace industry has been gaining attention. The poor surface quality of parts greatly limits the prospects of MAM-produced parts in the aerospace industry as fatigue performance hinges on a good surface finish and homogeneous microstructure. Post-processing treatments are important to improve the surface quality and the overall performance of MAM-produced parts during static and dynamic loadings. This paper provides a review of the current state of post-processing treatment options for MAM-produced parts. The advances in the post-processing treatments of MAM parts to improve fatigue strength, tensile strength, surface integrity and other properties of parts are reviewed. Future research prospects on metal additive manufacturing of aerospace parts are briefly expounded.
