Descripción del proyecto
Un estudio podría ayudar a mejorar la capacidad de almacenamiento de hidrógeno y la estabilidad de las aleaciones de magnesio y niobio
La creación de aleaciones sostenibles con un rendimiento excepcional es esencial para la cuarta revolución industrial y la reducción de las emisiones nocivas de CO2. En el proyecto SHSBALMBNA, financiado por las acciones Marie Skłodowska-Curie, se prevé utilizar el nuevo método de forja por plegado acumulativo, por el cual el metal se pliega, forja y recuece, para mejorar la capacidad de almacenamiento de hidrógeno en una aleación de magnesio y niobio (Mg/Nb). Ello implicará un refinamiento de grano extremo y la síntesis de una estructura de nanocapas. También requerirá diseñar un sistema de estratificación avanzado para la creación de nanogranos y la aleación forzada entre Mg y Nb. Los materiales resultantes se caracterizarán en términos de características estructurales, propiedades mecánicas y comportamiento funcional. Por último, se emplearán modelos a escala atómica para simular el rendimiento del almacenamiento de hidrógeno.
Objetivo
The generation of advanced alloys with extraordinary sustainable, functional performance is a game changer for commercializing advanced manufacturing technologies and is a key issue for the 4th industrial revolution, considering the environmental issues to reduce CO2 emission, as well. To this end, thermally stable, high-performance bulk nanostructured (nano-layered) nanocomposites containing stable interfaces are highly desirable for hydrogen storage. Within the proposed project, the newly developed accumulative fold-forging (AFF) method shall be applied to enhance the hydrogen storage response of a Mg/Nb alloy based on extreme grain refinement down to the nano-scale and the synthesis of a nano-layered structure. This novel alloy design will assess this synergy between advanced manufacturing by a novel severe plastic deformation (SPD) approach and metal physics as an interdisciplinary topic. First, the advanced layered system will be designed by AFF for nano-grains formation and forced alloying between Mg and Nb. Then, the manufactured new materials shall be characterized in terms of structural features, mechanical properties, and functional behaviour. Third, atomic-scale structural modelling will proceed to simulate sustainable hydrogen storage performance. These experiments may give novel insights into tailoring the pathways toward sustainable microstructural design for optimizing the composition and structure of advanced Mg/Nb nanostructured alloys with extraordinary storage capacity and cyclic stability. Coming from the world-foremost centers on advanced manufacturing and alloy design, I will bring new scientific and technological knowledge to the host university and institute. Meanwhile, practical training at one of Germany’s best universities and research institutes, progressing the current state-of-the-art by developing metal physics of advanced nanostructured alloys and high-quality publications, can prepare me for a professorship position in the EU or NA.
