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…

Seminar Marta Serrano: Structural materials for Gen IV reactors

Marta Serrano García (CIEMAT) The next evolution for commercial nuclear reactors include the design of fast nuclear reactors as a sustainable nuclear energy production system. The operating conditions for this Gen IV reactors are much more aggressive than the ones for operating light water reactors, in terms of neutron dose, temperature and coolants, that rise the need to explore new structural materials able to sustain this conditions. In this talk, a review of the potential degradation mechanisms and related design…

Seminario Oscar Ruano: Aspectos fundamentales de la fluencia de materiales

Dr. Oscar Ruano: Profesor de Investigación, Departamento de Metalurgia Física, CENIM-CSIC El seminario que tuvo lugar el pasado día 15 de diciembre en IMDEA Materiales abordó la fluencia de los materiales de una manera simple, resaltando los aspectos fundamentales y haciendo hincapié en los equipos y las curvas que determinan su comportamiento.  También en los parámetros mecánicos que se obtienen a partir de los datos experimentales. También se mostraron las pautas para una asociación de dichos parámetros con los mecanismos…

Seminar Dr. Isaac Toda-Caraballo: An overview on the designing High Entropy Alloys

Dr. Isaac Toda-Caraballo: Department of Materials Science and Metallurgy. University of Cambridge (UK) Within the last two decades, a new type of material has been increasingly explored. Widely known as High Entropy Alloys (HEAs), they contrast with most of the existing metallic materials in which they do not contain a major element, such as steels, aluminium alloys or magnesium alloys. Their original definition assumes 5 or more different elements, with composition between 5% and 35% of atomic content, displaying a…

Seminar Dr. Alexander Zhilyaev: Bulk nanostructured materials processed by severe plastic deformation: from fundamentals towards applications

Dr. Alexander Zhilyaev: Fundació CTM Centre Tecnològic (Spain) and Institute for Metals Superplasticity Problems of Russian Academy of Science (Russia) In recent years, the development of bulk nanostructured materials (BNM) has become one of the most fascinating directions in modern materials science. One method of nanostructuring is the “top-down” approach which is based on grain refinement through heavy straining or shock wave loading. During the last two decades, grain refinement by severe plastic deformation (SPD) techniques has attracted special interest…
