“…AM processes such as SLM or EBM present some undesirable effects or limitations. The latest research is looking further into WAAM processes and their relationship to corrosion resistance [129], as well as new and recently-developed µ-plasma arc additive manufacturing process, which are quite promising [130].…”

Additive manufacturing is an important and promising process of manufacturing due to its increasing demand in all industrial sectors, with special relevance in those related to metallic components since it permits the lightening of structures, producing complex geometries with a minimum waste of material. There are different techniques involved in additive manufacturing that must be carefully selected according to the chemical composition of the material and the final requirements. There is a large amount of research devoted to the technical development and the mechanical properties of the final components; however, not much attention has been paid yet to the corrosion behaviour in different service conditions. The aim of this paper is to deeply analyze the interaction between the chemical composition of different metallic alloys, the additive manufacturing processing, and their corrosion behaviour, determining the effects of the main microstructural features and defects associated with these specific processes, such as grain size, segregation, and porosity, among others. The corrosion resistance of the most-used systems obtained by additive manufacturing (AM) such as aluminum alloys, titanium alloys, and duplex stainless steels is analyzed to provide knowledge that can be a platform to create new ideas for materials manufacturing. Some conclusions and future guidelines for establishing good practices related to corrosion tests are proposed.

The 3D‐printing of high‐entropy alloys (HEAs) is capable of enhancing the design and manufacturing flexibilities for the novel materials. Owing to the rapid solidification, the 3D‐printed HEAs exhibit markedly different microstructures than their conventionally‐manufactured equivalents, leading to peculiar mechanical properties. Many additively‐manufactured HEAs also break down the strength‐ductility trade‐off dilemma. Novel dynamics regarding the simultaneous and sequential nature of deformation mechanisms are emerging through recent intensive research on these materials. Herein the deformation behavior of 3D‐printed HEAs is reviewed and explained on the basis of the latest advances in this area. A comprehensive picture regarding the role of cellular dislocation networks, twinning‐induced plasticity (TWIP), and transformation‐induced plasticity (TRIP) in the monotonic and cyclic deformation of 3D‐printed HEAs is presented. Special emphasis is placed on fatigue characteristics due to the enormous interest in this burgeoning area. The effect of post‐fabrication thermomechanical processing on plasticity is discussed along with the microstructural evolution in the 3D‐printed HEAs. Several innovative developments that carry latent potential for further research are also deliberated in this review. Finally, the present understanding of the deformation behavior of 3D‐printed HEAs is summarized while gauging the future directions.This article is protected by copyright. All rights reserved.
