Abstract Diffusion-bonding of TiAl (48 at.% Al) using both solid-state and transient-liquid-phase (TLP) processes was studied. In solid-state diffusion-bonding, dynamic recrystallization which occurs at the bond-line during bonding is found to have a significant effect on improving bond strength.

Abstract The goals of modeling diffusion bonding can be regarded as twofold: to optimize the selection of the process variables for a given material and to provide an understanding of the mechanisms by which bonding is achieved. This article describes the existing models of diffusion bonding with an assumption that the surfaces to be ...

Worldwide there is a trend to use diffusion bonding for more and more applications, for example for optical components, micro devices and heat transfer elements. Despite that the market for diffusion bonded product is still small today, more than 30 companies offer diffusion bonding systems worldwide.

There is currently great interest in the process of diffusion bonding. The main thrust has been in the joining of advanced materials such as superplastic alloys, metal matrix composites and ceramics and, most importantly, to introduce the process into mass-production operations.

Diffusion doping in quantum dots: bond strength and diffusivity
Nanoscale, 2017Semiconducting materials uniformly doped with optical or magnetic impurities have been useful in a number of potential applications. However, clustering or phase separation during synthesis has made this job challenging. Recently the "inside out" diffusion doping was proposed to be successful in obtaining large sized quantum dots (QDs) uniformly doped ...

SITE- AND BOND-DIFFUSION ON REGULAR LATTICES
International Journal of Modern Physics B, 2009We consider two types of motion, one with particle occupying only the sites on a given regular lattice and another when the bonds between neighboring lattice sites are displaced to the positions of the neighboring bonds. We refer to these models as site- and bond-diffusion.

Diffusion bonding: development of theoretical model
Metal Science, 1984In previous work, a theoretical model for solid state diffusion bonding was described. The vapor phase mass transport rate equations are now derived. In addition, a revised model is presented for the power law creep mechanism based on considerations of the elastic and plastic deformation of a long triangular ridge.

Diffusion Bonding — An Overview
1991Diffusion bonding is a microdeformation solid phase process finding application in niche areas. The mechanisms of bonding are generally understood, and data on modelling is available although limited to simple metal systems.

Low-Pressure Diffusion Bonding of Titanium
Journal of Spacecraft and Rockets, 1978This paper describes a new manufacturing process for diffusion bonding of titanium alloys. The technique requires the use of high-vacuum furnaces, but allows bonding to be carried out at very low contact pressures. This is possible because the parts are kept separate during outgassing through the innovative use of glass tooling.

Diffusion bonding of mismatch dental alloys
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2009AbstractThe diffusion bonding of Ti‐6Al‐4V and Co‐Cr‐Mo dental alloys has been investigated in terms of the atoms diffusion, the microstructure evolution, and the bonding strength. The bonding performance reveals asymmetry diffusion profiles for both the Co and Cr in Ti‐6Al‐4V and the Ti in Co‐Cr‐Mo alloy.
