Brittle defects, such as continuous intermetallic compounds and straight bonding line
composed of grain or phase boundaries, often form at the interface of dissimilar metals …

Enhanced Hastelloy alloy diffusion bonding was investigated via introducing nanostructured
Ni surface layer. Because the bonding temperature was significantly higher than the …

Solid-state bonding shows irreplaceable advantages in joining similar and dissimilar
materials with poor weldability compared with fusion welding methods. To widen its …

The nickel-based superalloy GH4099 was diffusion-bonded with 2–10 μm thick pure nickel
interlayer. The joint microstructure was characterized by scanning electron microscopy …

Directional solidification (DS) of intermetallic compounds Ni 3 Al based superalloys were
joined by solid-state diffusion bonding (SSDB) with the joining interface perpendicular to the …

This study focuses on the microstructure evolution and mechanical properties of dual metal
diffusion bonded joints formed between Haynes 230 Ni-based superalloy bars and Haynes …

Ni 3 Al-based alloys were direct diffusion bonded to themselves at 950–1100° C for 10–
60min under a pressure of 20 MPa. The effects of the joining parameters on shear strength …

The development of a compact-type heat exchanger is one of the critical issues for realizing
an efficient gas-to-gas heat exchanging system in a very high-temperature gas-cooled …

The mechanical properties of diffusion bonded joints embodied from 29 different kinds of
alloys obtained from experiments (37 specimens) or literature (194 specimens) were …

In this study, the FGH98 superalloy and DD5 single crystal were diffusion bonded using pure
Ni interlayer under the pressure of 4 MPa. The elemental interdiffusion of Ni interlayer and …
