摘要: The metadynamic recrystallization behaviors in deformed 2124 aluminum alloy were investigated by isothermal interrupted hot compressive tests, which carried out at the deformation temperatures of (653–743) K, strain rates (0.01–10) s−1 and inter-stage delay time (30–180) s. A new approach, “peak stress method”, is proposed to calculate softening fractions induced rapid recrystallization. kinetic equations developed predict compressed alloy. Both experimental predicted results show that effects parameters, including rate, degree temperature, on two-pass are significant. good consistency between indicates can precisely estimate kinetics
