Project description
Advanced alloy powders for strong, durable materials without cracks or flaws
Creating materials that are both strong and ductile is a long-standing challenge in material science. Architecturally heterogeneous multi-material composites, which combine different materials with tailored structures, offer a way to overcome this. Yet, traditional high-temperature methods often cause cracking and uneven material properties. With the support of the Marie Skłodowska-Curie Actions programme, the E-AH-MMEAC project will introduce a new approach to mitigate these challenges. The proposed method involves first forming billets from multi-principal element alloy powders (made from multiple principal elements mixed in near-equal proportions) using cold spraying, followed by friction stir processing to refine the material structure. E-AH-MMEAC will focus on optimising the process, studying material performance under different conditions and elucidating how its structure affects its behaviour.
Objective
Architecturally heterogeneous multi-material multi-principal element alloy (MPEA) composites represent a unique class of heterostructured materials with great potential to evade the strength–ductility trade-off dilemma. However, most conventional processing routes involving high temperatures (e.g. casting, additive manufacturing, and powder metallurgy) suffer from various metallurgical issues such as excessive elemental diffusion, segregation, hard intermetallic phase formation, cracking, and poor densification. To mitigate these challenges, the project suggests prefabricating various MPEA powders into billets using cold spraying (CS) and then employing solid-state friction stir processing (FSP) to achieve microstructural densification. This approach will initiate various dynamic recrystallizations in different compositional domains, allowing us to engineer architecturally heterogeneous multi-material MPEA composites. In general, this project will be implemented in phases, including optimizing process, controlling the heterostructure, evaluating mechanical performances from ambient to cryogenic temperatures, and elucidating deformation mechanisms. The results can be expected to build up the “processing–microstructure–mechanical behavior” correlations of the newly developed multi-material MPEA composites in a quantitative manner. This will facilitate the design and fabrication of similar heterostructured composites, thereby impacting a wide range of industrial sectors, e.g. transport, defense, nuclear, and manufacturing.
