Partially recrystallized precipitation-hardened high entropy alloys have shown excellent mechanical properties with yield strength up to 2 GPa. However, the recrystallization kinetics of precipitation-hardened high entropy alloys are not adequately revealed due to the complex interactions between precipitation and recrystallization. Here, we report an abnormal recrystallization behavior of precipitation-hardened high-entropy alloys that the recrystallization kinetics at 600 °C are faster than those at 800 °C. Moreover, the recrystallization period at 800 °C is significantly shorter than that at 600 °C. Through comparative analysis, we attributed the abnormal recrystallization kinetics to the delayed pinning effect caused by slow precipitation kinetics at 600 °C while the shortened recrystallization period to the high recrystallization nucleation rate by particle-stimulated nucleation at 800 °C.
