Abstract The precipitation behavior of the γ″ phase and mechanical properties in Inconel 718 alloy during aging under an external applied stress or internal quench-in residual stress were studied. The results show that nucleation and precipitation of the γ″ phase are strongly promoted by external stress in the early stages of aging. The γ″ precipitates exhibit homogeneous nucleation and always maintain a coherent relationship with the matrix. Further, the competitive growth of γ″ particles… CONTINUE READING
