ALLVAC 718 Plus™ Superalloy for Aircraft Engine Applications

A study on developing process-structure–property relationship with molten pool thermal history during laser surface remelting of Inconel 718

“…Inconel 718 is a nickel-based superalloy, and because of its superior high-temperature microstructural stability, it is widely used in the aerospace industry for making high-pressure turbine blades and components in the hot sections of rocket engines such as combustion chamber inlet, turbine and pre-burner exhaust [1,2]. With prolonged usage, these components are subjected to wear and tear.…”

Effect of Nanocrystalline Nickel Powder and Co, Mo, Ta, and Al Additions on Isothermal Oxidation Behavior of Ni–17Cr Alloy

“…Nonetheless, the impact of the alloying elements is still open to discussion. In addition, conventional processing such as induction melting and isostatic pressing just to name a few have been reported to induce defects such as microsegregation, grain growth, and inclusions of nonmetallic material in the alloy which results in adverse alloy properties [1,15]. Thus, these limitations contribute to the poor oxidation performance of nickel-based alloys while in service.…”

Recrystallisation behaviour and mechanical properties of a novel Re-containing nickel-base superalloy

“…Nickel-base superalloys are widely used for critical structural components in gas turbine engines (GTE) such as high-pressure discs. To improve the fuel efficiency of GTE, it is of great importance to develop new Ni-based superalloys to withstand higher operating temperatures and loadings [1–3]. Regarding polycrystalline nickel-base superalloys, which are the most competitive from the viewpoint of the production cost, novel nickel-base superalloys are often designed towards heavier alloying [1–11].…”

“…To improve the fuel efficiency of GTE, it is of great importance to develop new Ni-based superalloys to withstand higher operating temperatures and loadings [1–3]. Regarding polycrystalline nickel-base superalloys, which are the most competitive from the viewpoint of the production cost, novel nickel-base superalloys are often designed towards heavier alloying [1–11]. Particularly, the alloy designing approaches include an increase in the volume fraction of the γ′ phase precipitates by increased concentrations of precipitate forming elements [1,2], heavy alloying with elements providing effective substitutional solid solution strengthening and a higher γ′ solvus temperature [1,4–6] etc.…”
