New joint project: ADITIMAT network granted by Spain’s National Research Plan

Three groups of ADITIMAT-CM have been granted to study the integrity and reliability of materials processed by additive manufacturing techniques.

The project MICRO-Matters@AM points the relevance of the structural integrity and durability when safety is critical for the application of additive manufacturing (AM) techniques

The Groups EME–UPM, GTP–UC3M and COL–CSIC, participants at the ADITIMAT–CM network, along with the CIFEMA-UPM group, have achieved 447.700€ from the Spanish Agency of Research to develop during the next 3 years the project entitled “Structural integrity at different length scales of novel ceramic/metal composites processed by additive manufacturing (MICRO-Matters@AM)”.

The project points out the relevance of the structural integrity and durability when safety is critical for the application of additive manufacturing (AM) techniques in industrial sectors such as building, transport or biomaterials. The intrinsic layer to layer characteristics and the adaptive modifications of powder processing techniques requires of a global vision of the material deposition cycles for enhanced the referred correlations among Structural Integrity – AM technology – Microstructure/Material assemblage issues. Indeed, this defines the main challenge behind MICRO-Matters@AM and, as every new advance in the Materials Science & Engineering field, to address it satisfactorily requires the interaction of groups whose expertise is complementary regarding processing, characterization and property/performance evaluation from a multiscale perspective.

Adapting chemical, nanostructural and microstructural features to the processing technologies under consideration as well as to needs to be demanded by the service conditions imposed by its application. In this regard, it should be highlighted that performance, either as structural or as a functional material, is directly associated with (and is often limited by) structural (including microstructure) integrity at all length scales. This is particularly true when considering new processing routes, like those based on AM.

Within the above context, this project combines the efforts and resources of the four research groups in: (1) manufacture of ceramic-metal composite materials following novel routes based on AM; (2) implementation of advanced and reliable characterization protocols for assessment of microstructural and mechanical integrity, the latter at both macro- and micrometric scales; (3) microstructural design of novel ceramic-metal systems and use of environmentally clean chemical processes, based on targeted AM technologies; and (4) consideration of damage tolerance as a structural integrity approach for reliability enhancement of advanced materials under defined service-like conditions (i.e. exposure to high temperatures, corrosion media or contact loads).

All these research activities are to complement the interdisciplinar and intersectorial framework that ADITIMAT-CM provides to its members.
