An evolution law of δ phase of IN718 superalloy in temperature/stress coupled feld is studied in the present research. The results show that the δ phases accelerate precipitates on the grain boundaries with applied stress. In the temperature/stress coupled feld, both the nucleation and growth rate of a δ phase will be signifcantly accelerated with stress. The increasing driving force of nucleation depends on the increase of the strain energy and reduction of the system free energy, promoting nucleation of the δ phase. The high growth rate is caused by increasing the joint phenomenon of the adjacent same-oriented δ rods with the coupled action of the temperature and stress.
