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.

“…Throughout the entire SLM process, a high-purity argon (Ar) atmosphere was used, ensuring that the oxygen content remained below 100 ppm. A Ti-6Al-4V plate was served as the building substrate and preheated to 393 K. Based on our previous studies, 7,16 samples were produced with the parameters as follow: a scanning speed (v) of 1100 mm/s, laser power (P) set at 175 W, a layer thickness (d) of 30 μm, and a scanning distance (h) of 30 μm. Wire cutting was utilized to separate metal specimens from the plate, followed by 30-min ultrasound washing and drying in a vacuum drying oven.…”

In this work, porous Ti‐15Mo scaffolds with different porosity gradient structures (uniform gradient structures [U‐BCC], level gradient structures [LG‐BCC], and vertical gradient structures [VG‐BCC]) were fabricated by selective laser melting, and the corrosion fatigue testing in Hank's solution was conducted for the first time. The fatigue strength order, when considering the same fatigue life, follows the sequence of LG‐BCC structure > U‐BCC structure > VG‐BCC structure. Cyclic ratcheting is a prominent factor leading to fatigue failure. The sequence of crack initiation and propagation in the latter stage of corrosion fatigue can be listed as follows: LG‐BCC structure < U‐BCC structure < VG‐BCC structure. During the corrosion fatigue process, the grain refinement occurs, and the deformation twinning is generated, leading to a dissipation of energy and an increase of the fatigue resistance. The corrosive effect of Hank's solution induces the surface roughening of the sample, accelerating crack initiation and propagation.
