TLDR
In this article, the authors investigated diffusion bonding of titanium, steel and copper alloys used in the fabrication of several aerospace components with various complex configurations, including high pressure tanks for attitude control of spacecraft, a combustion chamber with copper cooling channels and lightweight structural panels.Abstract:
Diffusion bonding is a solid-state bonding process The metal components being joined undergo only microscopic deformation, and the joining region is homogeneous – without secondary materials or liquid phases This chapter investigates diffusion bonding of titanium, steel and copper alloys used in the fabrication of several aerospace components with various complex configurations The result shows that the diffusion-bonding method can be successfully used with blow forming to form near-net-shape aerospace components, including high-pressure tanks for attitude control of spacecraft, a combustion chamber with copper cooling channels and lightweight structural panelsread more

The kinetics of isostatic diffusion bonding in superplastic materials
TL;DR: In this paper, a model has been developed to predict the time required to attain full interfacial contact during diffusion bonding under an isostatic state of stress, and it has been shown that the reduction of the long-range waviness of the surfaces plays as significant a part in the bonding process as does the closure of the short wavelength roughness.
