L12 phase hardening alloys with excellent mechanical properties are of great significance
for structural applications. However, low volume fractions of L12 precipitates in conventional …

In this work, by using multi-scale characterizations from electron channeling contrast
imaging (ECCI) to atom probe tomography (APT), we directly evidenced that the massive …

IN738LC superalloy, as one of the hard-to-weld Ni-based superalloys, is relatively difficult to
produce by laser powder bed fusion (LPBF) due to its high cracking susceptibility. In this …

Avoiding cracking defects is crucial to ensuring processability in the laser powder bed fusion
(LPBF) of metallic materials. In this study, a crack-free Ni-based superalloy with a high …

Nickel-based superalloys (Ni-alloys) are widely used in flight critical aeroengine
components because of their excellent material properties at high temperatures such as …

The nickel-based superalloy, Haynes 230 (H230), is widely used in high-temperature
