Opis projektu
Ekologiczne i tanie superstopy kobaltu i niklu
Superstopy to stopy charakteryzujące się doskonałą wytrzymałością i odpornością na wysokie temperatury. Superstopy na bazie kobaltu wzmacniane fazami γ’ cieszą się dużym zainteresowaniem ze strony producentów zaawansowanych silników odrzutowych, którzy chcą zastąpić nimi stosowane dotychczas superstopy na bazie niklu. Ich wytwarzanie nastręcza jednak obecnie wielu trudności. Zespół finansowanego w ramach działania „Maria Skłodowska-Curie” projektu CNSTech zamierza opracować superstopy na bazie niklu i kobaltu, wykorzystując w tym celu zaawansowane metody metalurgii proszków. Wielodyscyplinarne badania obejmą modelowanie termodynamiczne, metalurgię chemiczną i fizyczną, przetwarzanie materiałów i doświadczenia.
Cel
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.
