Deformation Behaviors

Hot-rolling direct quenching and dynamical partitioning (HDQ&DP) processes were applied to a low-carbon steel containing silicon and manganese based on thermo-mechanical control process (TMCP) technology and ultra-fast cooling (UFC) technology. The microstructures and phase compositions were characterized and analyzed using SEM, EBSD, TEM and XRD. The mechanical properties and tensile deformation behaviors were investigated by means of uniaxial tensile test. The microstructures and tensile deformation behaviors of both HDQ&DP steel with and without proeutectoid ferrite were comprehensively expounded by comparing with each other. Results show that the amount of retained austenite in the HDQ&DP steel with proeutectoid ferrite can reach up to 17.3%, which is higher than that in the HDQ&DP steel without proeutectoid ferrite (15.7%). The HDQ&DP steel without proeutectoid ferrite possesses extremely high ultimate tensile strength (UTS) up to 1700 MPa with yield ratio about 0.73 and elongation about 11.5%. The introduction of proeutectoid ferrite can result in a moderate decrease of UTS to 1240-1400 MPa, a drastic decrease of yield ratio to 0.51-0.69 and a certain increase of elongation to 13.0-13.7%. The existence of the proeutectoid ferrite can partly enhance the work hardening ability of the steel and may improve its formability. It is concluded that the HDQ&DP steel with relatively large amount of proeutectoid ferrite and certain amount of bainite has extensive application prospects.

Hot-rolling direct quenching and partitioning (HDQ&P) processes were applied to both low carbon high silicon vanadium micro-alloyed steel and low carbon low silicon steel with phosphorus addition. Proeutectoid ferrite with an area fraction of about 30% was introduced into some of the sheets. Microstructures were characterized using SEM, TEM and XRD. Mechanical properties were investigated by means of uniaxial tensile test. Austenite stabilization, retained austenite stability, tensile deformation and fracture were comprehensively analyzed by making the comparison between the two steels and between the sheets with and without ferrite considering the different precipitation statuses in ferrite. Experimental results showed that the high silicon vanadium micro-alloyed steel contained more retained austenite with higher stability compared with the low silicon phosphorus added steel. Filled with much more carbides with larger sizes, the martensite in the low silicon phosphorus added steel exhibited a much salient tempered feature. The high silicon vanadium added steel possessed higher strength and ductility than the low silicon phosphorus added steel. The introduction of ferrite can result in an extremely obvious post-necking elongation drop in the low silicon phosphorus added steel. The dispersed V-bearing precipitates and high silicon content in ferrite can increase the yield strength and simultaneously diminish the hardness difference between ferrite and martensite, which can improve their compatible deformation capability and then enhance the work hardening ability and finally raise both the UTS and elongation of the steel.

300M Steel

To investigate the effect of hot working parameters on the flow behavior of 300M steel under tension, hot uniaxial tensile tests were implemented under different temperatures (950 °C, 1000 °C, 1050 °C, 1100 °C, 1150 °C) and strain rates (0.01 s−1, 0.1 s−1, 1 s−1, 10 s−1). Compared with uniaxial compression, the tensile flow stress was 29.1% higher because dynamic recrystallization softening was less sufficient in the tensile stress state. The ultimate elongation of 300M steel increased with the decrease of temperature and the increase of strain rate. To eliminate the influence of sample necking on stress-strain relationship, both the stress and the strain were calibrated using the cross-sectional area of the neck zone. A constitutive model for tensile deformation was established based on the modified Arrhenius model, in which the model parameters (n, α, Q, ln(A)) were described as a function of strain. The average deviation was 6.81 MPa (6.23%), showing good accuracy of the constitutive model.
