Nickel-based superalloys have been widely used in aerospace fields, especially for engine
hot-end parts, because of their excellent high-temperature resistance. However, they are …

Selective laser melting (SLM), an additive manufacturing process mostly applied in the metal
material field, can fabricate complex-shaped metal objects with high precision. Nickel-based …

Additive manufacturing offers an exclusive way of anisotropic microstructure control with a
high degree of freedom regarding variation in process parameters. This study demonstrates …

Additively manufactured high-entropy alloys generally suffer from low strength and/or poor
ductility. In this work, by leveraging the good castability of eutectic high entropy alloys and …

Four types of scanning strategies, ie 0°, 90°, 67° hatch angle and a chessboard with 67°
hatch angle strategy (CB+ 67°), were adopted to study the microstructure and mechanical …

Irregular large pores induced by laser powder bed fusion (LPBF) are inherent defects, which
greatly domain the mechanical properties of as-built components. Laser remelting is an …

The microstructure and mechanical behaviors of as-built Inconel 625 prepared by selective
laser melting (SLM) and laser engineered net shaping (LENS) technologies were …

In this study, a GH3536 nickel-based superalloys was fabricated by the laser powder bed
fusion technology (LPBF) with emphasis on its microstructure evolution and mechanical …

In this paper, the effect of microstructural anisotropy on the fatigue crack growth behaviour of
the functionally graded Inconel 718 fabricated through laser powder bed fusion (L-PBF) is …

Heat treatment is a key process governing the final microstructure and mechanical
properties of precipitation-hardened superalloys. However, traditional heat treatments are …
