Diffusion Bonding and Brazing of Advanced Materials

Dear Colleagues,

Advanced materials generally require the development of novel joining techniques, as this is crucial to integrate them into functional structures and to widen their application field. Additionally, joining constitutes a technology, which influences all the industrial sectors, playing a key role in the economic and social development of a country.

Diffusion bonding and brazing are two straightforward techniques for producing sound and reliable joints since these processes are capable of joining a wide range of materials of interest in the aerospace industry, as well as in many other industrial applications, offering remarkable advantages over conventional fusion welding processes.

Production of dissimilar joints is also crucial for application of these materials. For instance, the combination of advanced ceramic with lightweight alloys, such as titanium or aluminium alloys, is quite attractive, combining the extraordinary properties of the two materials and extending the potential applications particularly into components for the automotive and aerospace industries. The major challenge in the production of these joints is to overcome the enormous differences in mechanical behaviour, as well as thermal expansion coefficients and so new approaches need to be developed to produce dissimilar joints successfully.

This Special Issue aims at showcasing the recent progresses in the joining technologies of advanced materials, with a particular attention for the microstructure–mechanical properties relationships of the bonded joints. Both theoretical and experimental research, review articles, and novel results are welcome.
