Mechanical and Microstructural Characterization of Arc-Welded Inconel 625 Alloy. [PDF]
Materials (Basel), 2019 The objective of this work was to verify a relatively new fusion-based additive manufacturing (AM) process to produce a high-temperature aerospace material. The nickel-based superalloy Inconel 625 (IN625) was manufactured by an arc-based AM technique. Regarding microstructure, typical columnar-oriented dendritic structure along the building direction ...

Effect of Fe Content on Microstructure and Properties of Laser Cladding Inconel 625 Alloy. [PDF]
Materials (Basel), 2022 Dilution rate is one of most important factors influencing the microstructure and performance of the laser cladding layer. In order to obtain a reasonable dilution rate in the laser cladding layer of Inconel 625 alloy, the laser cladding layers with different Fe content were prepared on the surface of 20# steel by the laser cladding technique.

Solid-State Transformation of an Additive Manufactured Inconel 625 Alloy at 700 °C. [PDF]
Appl Sci (Basel), 2021 Inconel 625, a nickel-based superalloy, has drawn much attention in the emerging field of additive manufacturing (AM) because of its excellent weldability and resistance to hot cracking. The extreme processing condition of AM often introduces enormous residual stress (hundreds of MPa to GPa) in the as-fabricated parts, which requires stress-relief heat

Deformation Behavior of Inconel 625 Alloy with TPMS Structure. [PDF]
Materials (Basel)Triply periodic minimal surfaces (TPMSs) are known for their smooth, fully interconnected, and naturally porous characteristics, offering a superior alternative to traditional porous structures. These structures often suffer from stress concentration and a lack of adjustability. Using laser powder bed fusion (LPBF), we have fabricated Inconel 625 sheet-

The Interface Microstructures and Mechanical Properties of Laser Additive Repaired Inconel 625 Alloy. [PDF]
Materials (Basel), 2020 The microstructure and micro-mechanics around the repaired interface, and the tensile properties of laser additive repaired (LARed) Inconel 625 alloy were investigated. The results showed that the microstructure around the repaired interface was divided into three zones: the substrate zone (SZ), the heat-affected zone (HAZ), and the repaired zone (RZ).
