Modern day technology demands consistent and frequent advancements in materials for specialized applications. Nickel aluminide is one of such materials with distinctive properties that make them particularly suitable for high temperature applications especially in aerospace industries. However, the lack of ambient temperature ductility of this intermetallic has greatly restricted its applicability in service. In this review, the various efforts of researchers in solving this major limitation of nickel aluminides is evaluated and summarized, with particular emphasis on reinforcement types and processing methods that have been explored over the years.
