Abstract
In this presentation we discuss as case studies our results and experiments on very different nano structured bulk materials emphasizing the relationships between nano structuring and functional properties. Materials are solid electrolyte LSGM, hard B4C-based materials and doped MgB2 superconductor, and they are all fabricated by Spark Plasma Sintering (SPS). Among materials there are similarities, but also differences suggesting certain more general features, details and principles, while particular aspects should not be neglected. This analysis enables a better understanding on how the concepts of ‘transferability, ‘composite within a composite’, ‘multilevel design and multi functionality’ of the materials can be applied. SPS is reconfirmed as a powerful processing technique. SPS generates unique materials impossible to fabricate by other methods. However, SPS it is not universal and its suitability should be carefully considered depending on materials, their properties and targeted applications.
