<p>Y element affects hot workability and leads to cracking of alloys during forging, so that it is crucial to explore the effect of Y on the hot workability of Ni–Cr–Al superalloy to optimize hot working process. The hot deformation behavior is investigated by isothermal compression with the temperature ranging from 1050 to 1150 °C and strain rate ranging from 0.01 to 10 s⁻¹. The results show that flow stress increases first and then decreases as Y content rises. Strain-compensated Arrhenius constitutive equations are modeled for three Y-content superalloys, respectively, which could better predict flow stresses. During hot deformation, Y dissolving in matrix hinders dislocation movement and dynamic recrystallization growth. Meanwhile, Y refined grains and increased Ni₅Y phase, providing more dynamic recrystallization nucleation sites and driving force. Therefore, with the increase in Y element, dynamic recrystallization fraction shows the tendency to decrease first and then increase. Although excess Y has a facilitating effect on dynamic recrystallization, it leads to an increased risk of cracking due to excessive internal precipitation phases and grain boundaries.</p>
