Study of δ Phase on Static Recrystallization Behavior of Inconel 718 Alloy
The mechanical properties of Inconel 718 alloy depend on its microstructural features. Controlling the grain size during manufacturing is currently achieved through the use of a powerful hot forming process performed at a temperature sufficiently high to induce dynamic recrystallization.
The present study proposes an alternative technique to achieve a uniform fine grain structure by using static recrystallization and a proper control of δ precipitation. The results show that a fine structure with an average grain size of ASTM No. 7 can be achieved. And in this study
the finest grains yet achievable is ca. 200 nm. As a result, the proposed technique provides a feasible means of controlling the grain size without the need for an energy consumption and technically sophisticated hot forming process.
