Effect of cooling recrystallization annealing treatment on properties of an initial aged deformed GH4169 superalloy

In the authors’ previous study, a novel double-stage heat treatment method including an aging treatment and a cooling recrystallization annealing treatment (CRT) was proposed [1]. This method can evenly refine the deformed coarse grains of an initial solution-treated deformed GH4169 alloy. This study focuses on investigating the role of this method on the microstructural evolution and properties of an initial aged deformed GH4169 alloy. For the...
