Journal ArticleDOI
Microstructure and corrosion properties of CrMnFeCoNi high entropy alloy coating
TL;DR: In this paper, a single phase multi-component alloys up-to-date with promising mechanical properties at cryogenic temperatures, including corrosion resistance, is studied. But, the study on the corrosion behavior of CrMnFeCoNi HEA coating has still been lacking.
Journal ArticleDOI
Dendritic microstructure and hot cracking of laser additive manufactured Inconel 718 under improved base cooling
TL;DR: In this paper, the dendritic microstructure, crystal orientation and hot cracking behavior were studied by using optical microscopy, scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) techniques.
Journal ArticleDOI
Numerical study of keyhole dynamics and keyhole-induced porosity formation in remote laser welding of Al alloys
TL;DR: In this paper, the porosity formation takes three steps: bubble formation, bubble floating to the back of molten pool and bubble being captured by solidification front, and porosity prevention can be achieved by interrupting one of these three steps.
Journal ArticleDOI

TL;DR: In this article, the microstructure, hardness and wear resistance of Inconel 625 coatings were investigated at both room and elevated temperatures, and the results indicated that laser cladded inconel 675 coating has finer microstructures, alleviated segregation of Mo and Nb and lower dilution of iron compared with arc welded one as revealed by XRD, SEM and EDS.
Journal ArticleDOI
Formation and influence mechanism of keyhole-induced porosity in deep-penetration laser welding based on 3D transient modeling
TL;DR: In this paper, a 3D transient model is proposed to provide better insight into the correlations of dynamic keyhole behavior with porosity formation under various parameters, such as laser power, travel speed, and beam size.
