Microstructure evolution and anisotropy of nickel-based superalloy fabricated by LPBF

Microstructure evolution and anisotropy of nickel-based superalloy fabricated by LPBF

The microstructure evolution and anisotropy mechanism of IN738LC alloy under varying scanning speeds in laser powder bed fusion (LPBF) were investigated. Optical microscopy (OM) and scanning electron microscopy (SEM) were used to characterize the microstructural features, X-ray diffraction (XRD) was...
