The direct laser deposition (DLD) process has seen rigorous research in the past two decades due to its ability to directly manufacture products followed by minimal machining. The process input variables play a vital role in determining the properties achieved in the products manufactured by the DLD method. Inconel 625, a nickel-based superalloy with exceptional mechanical performance and corrosion resistance, has been used in critical applications within the aerospace, process, and marine industry. However, its poor machinability and higher load requirements for plastic deformation have been challenging for manufacturers. Therefore, many studies have explored the additive manufacturing of Inconel 625 to overcome these problems. This article focuses on the DLD of Inconel 625 and its composites, presenting the state-of-the-art, drawing a relation among laser processing parameters and resulting material properties, microstructure and phase evolution, and the high-temperature performance of DLD Inconel 625. The paper highlights the areas on which further studies may focus.

“…28 Because of their remarkable strength and oxidation resistance at temperatures above 550°C, nickel-based superalloys are widely used in the aerospace, aeronautical, petrochemical, chemical, and marine industries. 29 In recent years, various nickel-based superalloys, such as Inconel 718, 625 have been studied and utilized in the WAAM process. Inconel 625 is a nickel-based superalloy that derives its strength mainly from the solid-solution hardening effect of the refractory metals, niobium and molybdenum, in a nickel–chromium matrix.…”

In this article, Ni–Cr–Mo-based functionally graded material with a designed composition is successfully fabricated using the wire arc additive manufacturing process. The effect of the gradual variation of Ni, Cr and Mo concentration and the effect of high-temperature high-pressure deformation (HTHPD) in the different cooling environments on the morphology, microstructure, and mechanical properties along the gradient direction of the manufactured functionally graded materials (FGMs) have been investigated. With increasing Cr and Mo content from the bottom to the top, the FGM exhibits a gradual increase in tensile strength and microhardness. The hardness varies from 114 to 230, 130 to 205 and 164 to 256 HV for as-deposited, HTHPD with air-cooled (HTHPD-A) and HTHPD with water-cooled (HTHPD-W) samples, respectively, from bottom to top. Similarly, the average tensile strength is achieved at 793, 715 and 875 MPa in as-deposited, HTHPD-A and HTHPD-W samples, respectively. The microstructural examination of fabricated samples shows the columnar grain produced in as-deposited samples, deformed during the HTHPD process and recrystallized grains with orientation along the deformation direction has been formed.

The controlling strategies of grain morphology and mechanical properties of Inconel 625 alloy by laser powder bed fusion were investigated, and beyond that, the effects of phase composition, grain morphology and crystallographic texture on mechanical properties were also studied. The phase evolution was insensitive to the scanning strategies and all of the samples were composed of γ‐Ni phase. The (001) texture orientation tended to increase with the scanning rotation angle and the sample IV fabricated by scanning strategies of 90° shows the highest (001) texture. Different grain morphologies can be tailored by controlling the direction of heat flow between continuous layers via changing scanning strategies. The proportion of large elongated columnar crystals gradually decreases while the proportion of the equiaxed grains gradually increases as the scanning strategies change from 0°→90→ 67°→45°. The rotation angle increases from 0° to 45°, the ultimate tensile strength and yield strength increase from 1267±12MPa to 1304±5MPa and 760±10MPa to 801±5MPa, respectively, which is attributed to the different stress states presented in the columnar crystals and the equiaxed crystals.This article is protected by copyright.
