摘要	Due to the important role of d phase's quantity and morphology in the mechanical and fatigue properties of Inconel 718 alloy and its components, it is necessary to renew insights into the effect of cold deformation on the d phase precipitation, especially on the morphology evolution. Therefore, the nucleation and growth behavior of d phase in cold-rolled Inconel 718 alloy during aging were investigated. The results show that the precipitation rate and volume fraction of d phase increase with increasing the cold rolling reduction from 10% to 50%. The volume fraction of d phase reaches equilibrium after 5 h, remaining at 5.98%, 6.52%, and 6.79% under different rolling reductions (10%, 30%, and 50%), respectively. The nucleation of d phase mainly occurs on different sites (grain boundaries, new twin boundaries and old twin boundaries) under 10% rolling reduction, while d phase mainly nucleates on the new grain boundaries of static recrystallization due to 50% rolling reduction. And the growth of d phase undergoes a process of alternate orientation growth from spherical (nucleation) ? short rod (longitudinal orientation growth) -> short rod (radial orientation growth) ? dynamic equilibrium. Under 10% rolling reduction, d phase tends to grow into the matrix, while under 50% rolling reduction, the orientation grows faster and is easily affected by the grain boundary curvature.
