An Overview on Synthesis, Processing and Applications of Nickel Aluminides: From Fundamentals to Current Prospects

Nickel aluminides have desirable properties for use in high-temperature applications. certain qualities, but almost a decade the 1990s, those benefits were overshadowed by challenges of processing and machining at room temperature. Manufacturing improvements, increased knowledge aluminide microstructure deformation processes, developments micro-alloying all contributed to development nickel aluminides. Key aluminides, such as their microstructure, alloy addition development, are given discussed length. Methods production from past, ingot metallurgy investment casting melting addressed, powder metallurgy-based methods introduced. Finally, difficulties producing possible solutions examined. This paper gives an overview fundamentals, preparation, processing, applications current trends
