Descripción del proyecto
Superaleaciones a base de cobalto y níquel asequibles y ecológicas
Las superaleaciones son aleaciones de alta resistencia que soportan temperaturas elevadas. Las superaleaciones a base de cobalto reforzadas con precipitados de gamma prima han suscitado un gran interés para su uso en motores a reacción avanzados, como solución alternativa a las superaleaciones a base de níquel. Sin embargo, su producción resulta compleja. El objetivo del proyecto CNSTech, financiado por las Acciones Marie Skłodowska-Curie, es desarrollar superaleaciones a base de cobalto y níquel usando un método avanzado de pulvimetalurgia. Este estudio multidisciplinario incluirá modelización termodinámica, metalurgia física, metalurgia química, procesamiento de materiales y experimentos.
Objetivo
Improvement of the high temperature behavior of Ni based superalloys along the past decades was limited by approaching the gamma prime (γ′) solvus temperature to the Ni melting point. Although the benefits obtained were undoubtedly, their maximum operative temperature is a growing concern towards the sustainable development of advanced jet engine and gas turbine applications. Co based superalloys, strengthened by γ′ precipitates (with a L12 crystal structure), have recently attracted immense attention due to their excellent high temperature performance. They are considered an alternative to Ni-based ones if the stability and efficiency requirements are met. However, production of Co based superalloys via advanced sustainable manufacturing processes has several issues. CNSTech project proposes the development of the next generation Powder Metallurgy (PM) based CoNi superalloys via a sustainable metallurgy framework. The project will cover three stages: pre-build design, process design, and post-process design. First, thermodynamical modeling will be used to design an optimum and high entropy multicomponent CoNi based alloy. Then, modern powder technology (an entrance for advanced sustainable manufacturing processes such as PM and additive manufacturing) will be used for production. Finally, post-process design will be conducted via heat treatment, hot isotactic pressing, and process cost optimization. This multidisciplinary proposal covers a wide range of different fields including thermodynamical modeling, physical metallurgy, chemical metallurgy, materials processing, and design of experiments. By this multidisciplinary approach, CNSTech aims to open up new horizons to create a novel 100% European made processing route for manufacturing of cost-effective and eco-friendly high temperature CoNi superalloy towards the UN Sustainable Development Goals.
