主　　题：cold rolling precipitation (chemistry) kinetics Inconel 718 alloy δ phase 

摘      要：The volume fraction of δ phase in cold rolled Inconel 718 alloy aged at 910℃ for different times is measured by X ray diffraction techniques, and the influence of cold rolling on the kinetics of δ phase precipitation is investigated. It has been found that the relation between the volume fraction of δ phase and aging time follows the Avrami equation. With increasing cold rolling reduction, the value of n decreases and the value of a increases.
