The Study on Dynamic Response Mechanism of TRIP Steel in the Highest Strain Rate
In this paper, the dynamic mechanics property of TRIP steel in the strain rate range of 1 - 4000 S−1 was carried out. The material transformation process and mechanism in the high strain rate were analyzed. The TRIP effect was obvious in the strain rate range of 1500 - 2500 S−1. The excellent strain strengthening, strain hardening, and transformation strengthening were shown in the strain rate range of 1500 - 2500 S−1. TRIP steel has high dynamic yield strength, dynamic response and energy-absorbing capacity under the strain rate of 2000 S−1. The transformed amount and behavior of residual austenite affect the dynamic strength in different strain rates.
