On the modelling of diffusion bonding in materials: superplastic Super Alpha-2

Studies of microduplex Super Alpha-2 sheet have shown that the material has a considerable potential for superplastic deformation at temperatures in the range 940–980°C. Sound bonds were produced using isostatic pressure for different surface finishes at temperatures of 960 and 980°C under conditions which were fully consistent with the predictions of the model described in the paper, and within the limits of reliability of the materials property data available for Super Alpha-2.
