Seminar Eric Jägle: Alloys for Additive Manufacturing, Alloys by Additive Manufacturing

  Dr. Eric Jägle (Max Planck Institute of Metal Research in Düsseldorf, Germany)   As Additive Manufacturing technologies are being adopted in more and more industries, the focus of research and development is shifting to the materials in use. On the one hand, limited processability of high-performance materials restrict the robustness of the process in some cases, while in other cases the best materials for a given application cannot be processed at all. There is a strong need to modify…

Seminar Jorge Alcalá: Multi-scale mechanistic interpretations to indentation experiments across the material length scales: from continuum to atomistics

Prof. Jorge Alcalá (Universitat Politècnica de Catalunya) We provide a fundamental contact mechanics background to the interpretation of spherical indentation experiments performed in polycrystalline aggregates, single crystalline units, thin films, and minute material scales comprising an atomistic ensemble. A central issue under examination is the extraction of mechanical properties from hardness measurements as well as from instrumented indentation applied load-penetration depth curves performed in all such material lengths. Our analyses shed light into the role of the plasticity mechanisms (dislocation slip…

Additive alloy melting: Speeding up future alloy development

Miguel Cristóbal (IMDEA Materiales & CENIM, CSIC) Members of IMDEA Materials Institute and of the National Center for Metallurgical Research (CENIM-CSIC) are working together on the development of a novel method to accelerate the design of metallic alloys named Additive Alloy Melting, or ADAM. This method allows to limit significantly the time required to fabricate new alloys that meet the increasing demands of the energy, transport or biomedical sectors, which is currently carried out by costly and time consuming trial…
