Characterisation of diffusion bond TiAl–Ti 6242 joints

Entropie Characterisation of Diffusion*

A diffusion-related free energy has been used re­ cently [1-3] for the characterisation of diffusional behaviour [4-10]. In [2-3], this function has been evaluated numerically for typical model systems. However, in some sense the associated entropy func­ tion is able to give a more condensed picture of the system under investigation [11,12]. For a special class of chaotic systems related to a d...

Effect of Bond Thickness on Fracture Behaviour in Adhesive Joints

(2001) Effect of bond thickness on fracture behaviour in adhesive joints. To study the effects of bond thickness on the fracture behaviour of adhesive joints, experimental investigation and finite element analysis have been carried out for compact tension (CT) and double-cantilever-beam (DCB) specimens with different bond thickness. Fractography and fracture toughness exhibited apparent variati...

Effect of diffusion bonding temperature on microstructure properties of Zr/Ti interlayer in the diffusion bonded joints of Zr702 to A516 steel

In this study, the effect of temperature on the microstructure and reactive layer at the interface between the Ti interlayer and the base metal related to the diffusion bonding of Zr702 to A516 low alloy steel was investigated. The joining was done using the spark plasma sintering technique at temperatures of 900, 950 and 1000°C for 30 minutes. Field Emission Scanning Electron Microscope (FESEM...
