Rapid heat treatment simulation test of TRIP590 steel under different process conditions was conducted by using the continuous annealing simulation testing machine. The microstructure and mechanical properties of the steels were investigated by OM, TEM and tensile tester. The results show that the product of strength and plasticity is influenced the first by aging temperature, the second by annealing temperature in two phase region and the third by aging time. The best combination process is annealing at 850 ℃, and aging at 430 ℃ for 420 s, which could reach the most product of strength and plasticity.
