Mechanical properties of 34CrNi3MoA alloy steel are strongly influenced by both temperature and strain rate.
True stress exhibits a significant temperature-softening effect from 25 °C to 600 °C, while flow stress rises with increased strain rate.
A novel constitutive model was developed, integrating temperature and strain rate, significantly improving accuracy over the Johnson–Cook model.
The established model includes components for strain rate strengthening and temperature softening effects, showcasing their interdependence.
