“…This statement has also been demonstrated in the study of other materials [27–29]. To reduce the error between the calculated values and the experimental values, and establish a more precise constitutive model, therefore, it is necessary to modify the equation comprehensively by the strain compensation method [30]. The constitutive parameters corresponding to different strains, including and are calculated separately in the strain range of 0.015–0.825 with an interval of 0.045 and the results are listed in Table 2.…”

Hot working response of as-cast W12Cr4V5Co5 steel was investigated by isothermal compression testing in the temperature range of 1000-1150°C and strain rate range of 0.01-10 s −1 . Experimental results showed that the flow stress and microstructure evolution were susceptible to the hot deformation parameters. Work hardening first occurred at a small strain, followed by softening, and finally, an approximate dynamic equilibrium was achieved between work hardening and softening. The activation energy of deformation was calculated to be 557.33 kJ mol −1 , and constitutive equations compensated with strain were proposed to describe the flow stress as a function of deformation parameters. Microstructure analysis indicated that the average grain size decreased with the increase in strain rate and the decrease in deformation temperature. Additionally, the simulation of hot deformation via Deform-3D software revealed the sample's inhomogeneous deformation during hot compression. This study may provide guidance for hot working of as-cast W12Cr4V5Co5 steel.

“…The dominant softening mechanism transitions from dynamic recovery to dynamic recrystallization, As shown in Figure 4b, when the deformation temperature is increased to 1073 K, in addition to the elongation, twisting, and bending of the initial α lamellae, a large amount of dynamic recrystallization of the α phase occurs due to the higher-temperature and higher-recrystallization driving force. As the samples are quenched immediately after hot compression deformation, part of the β phase formed in the dual-phase temperature region undergoes martensitic transformation β!α 0 that results in the presence of a number of needle-shaped martensitic α 0 phase, [23][24][25] as shown in Figure 4c.…”

Isothermal compression experiments were conducted on Zr‐Sn‐Nb‐Fe alloy at temperature ranging from 873K to 1273K and strain rates ranging from 0.01s‐1 to 1s‐1. The deformation behavior and microstructure evolution were analyzed. The results show that the influence of α phase on the flow stress is more significant than β phase, which shows a stronger phase sensitivity. At low strain rates in the α phase temperature region (873K), the dominant softening mechanism is dynamic recovery, while at high strain rates, it controlled by dynamic recrystallization. The dual‐phase temperature region (973K∽1173K) undergoes the dynamic recrystallization of α and α→β phase transformation. The dynamic recrystallization of β occurs in the β phase temperature region (1213K∽1273K). Finally, by considering the phase composition and phase sensitivity differences, a unified constitutive model of N36 zirconium alloy from 873K to 1273K is established whose AARE is 7% and R is 0.9906.This article is protected by copyright.
