TL;DR: This review paper aims to provide an overview of the most significant achievements in WAAM, highlighting process developments and variants to control the microstructure, mechanical properties, and defect generation in the as-built parts; the most relevant engineering materials used; the main deposition strategies adopted to minimize residual stresses and the effect of post-processing heat treatments to improve the mechanical properties of the parts.

TL;DR: In this paper, the microstructure and mechanical properties of the as-built parts of HSLA steels are investigated, and are correlated with the thermal cycles involved in the process.

TL;DR: In this article, a functionally graded material (FGM) part was fabricated by depositing a Cu-based alloy on top of a high strength low alloy (HSLA) steel by twin-wire and arc additive manufacturing (TWAAM).

TL;DR: In this article, SiC particles were added to the molten pool during WAAM of a high strength low alloy steel, and the introduction of these high melting point particles promoted grain refinement and precipitation of Fe3C due to SiC dissociation.

TL;DR: In this article, a milling strategy which considers the microstructure and local mechanical properties of each part was employed, and the results showed that the mechanical behavior of the as-built parts does not yield a significant influence on the milling process.
