A study of yttrium‐modified aluminide coatings on IN 738 alloy
WebThe production of non-weldable nickel-based superalloys, especially single-crystal superalloys, is important for additive manufacturing. Single-crystal specimens of non-weldable nickel-based superalloys were produced by electron beam selective melting using an IN-738 alloy. WebAlloy IN-738 is normally vacuum melted and vacuum investment cast using procedures like those used for other high-strength, high-temperature nickel-base alloys. Typical casting … WebJan 7, 2024 · Inconel 738 is one of the widely used nickel-based superalloys in high-temperature applications, especially in land-based and aerospace gas turbine engines.
