چکیده
Abstract The flow behavior of a novel Cr-Si alloyed hot stamping steel (Cr-Si steel) at elevated temperature was investigated via isothermal compression tests on Gleeble-3500 thermomechanical simulator with range 600 ~ 900 ℃ and strain rate 0.1~10 s-1. Subsequently, the Arrhenius-type constitutive model, comprising compensation, established in accordance friction adiabatic heating corrected stress-strain curves. Furthermore, predictability prediction accuracy model were verified. results reveal that constant rate, stress initially increases as before tending to stabilize, owning combined effects work hardening dynamic recovery. peak stresses decrease temperatures increase rates decrease. can accurately predict relationship during process.

The grain boundary oxidation mechanism in hot rolled steel samples during cooling from 500 °C – 800 °C down to room temperature was mathematically modeled. Given a fixed temperature ramp, the migration of the atomic species (iron, oxygen and the alloying elements) has been calculated with the parabolic rate equation for diffusion. After each small time step, the data was transferred into the da...

The hot deformation behavior of a Fe–22Cr–25Ni–3.5W–3Cu–1.5Co super-austenitic stainless steel was investigated using isothermal compression tests with a wide range of temperatures (1173–1373 K) and strain rates (0.1–10 s). The results showed that all the flow curves gradually turned to balanced stress state without notable peak stress characteristics during the entire deformation, which indica...
