摘要：

The precipitation kinetic and behavior of delta phase in Inconel 718 alloy at 900, 930 and 960 degrees C have been studied using the quantitative X-ray diffraction (XRD) method. The results indicated that the nucleation site and way of delta phase depended on temperature by the observation of microstructures. During the aging process, the delta phase nucleated on the grain boundaries and twin boundaries preferentially, while the delta phase precipitated directly from the interior of grain when the temperature was above 900 degrees C. At a certain aging temperature, the relationship between the delta phase content and the aging time fitted an Avrami-type equation.
