Abstract
The microstructural features of diffusion bonded MA 956 joints were examined. It was found that the grain size and grain aspect ratio did not change after bonding. A toothlike structure was observed near the joint interface at higher bonding pressures. Large irregularly shaped particles were formed as a result of the interaction between dislocations and precipitates. A mechanism based on dislocation movement and interaction has been proposed to explain the formation of these particles. The distribution and size of yttria dispersoids remained unaffected under the bonding conditions investigated.
