“…The behaviour of the flow stress can be correlated to hot-working processes like dynamic recovery (DRV), dynamic recrystallization (DRX), and static recrystallization (SRX) [30]. The processes of dynamic recovery and recrystallization are considered the softening mechanisms during metal deformation [31]. DRX is a significant factor for controlling the mechanical properties and microstructure evolution during hot-working phenomenon [32][33][34].…”

The behaviour of plain carbon as well as structural steels is qualitatively different at different regimes of strain rates and temperature when they are subjected to hot-working and impact-loading conditions. Ambient temperature and carbon content are the leading factors governing the deformation behaviour and substructural evolution of these steels. This review aims at investigating the mechanical behaviour of structural (or constructional) steels during their strain rate (ranging from very low to very high) as well as hot-working conditions and subsequently establishing the structure–property correlation. Rate-dependent constitutive equations play a significant role in predicting the material response, particularly where the experiments are difficult to perform. In this article, an extensive review is carried out on the merits and limitations of constitutive models which are commonly used to model the deformation behaviour of plain carbon steels.

The effect of five cases of temperature-and-speed conditions in radial-shear rolling (RSR) of D16 alloy is analyzed. The temperature of the rod after each pass is obtained from the simulation results. With decrease in the heating temperature of the billet, the self-heating temperature of the rod during RSR increases. Depending on the selected temperature, rolling speed, reduction per pass, and rod dimensions, the temperature change relative to the initial heating can be more than 100 °C. The length and volume of the back-end defect are calculated for each of the temperature-and-speed conditions. With increase in the elongation ratio, the length of the back-end defect increases, and its volume decreases. The smallest back-end defect is observed in rods produced gradually decreasing the rolling temperature in each pass (for a 6 m rod, the scrap losses are 2.2% of the volume of rolled metal). For one of the temperature-andspeed conditions, the specific deformation energy consumption that does not exceed 24-35% of the total energy consumption is obtained. The rods produced by RSR have better strength and plasticity (σ B = 452-486 MPa, σ y = 262-290 MPa, δ = 13.0-16.5%) than those required by the GOST 21488-97 State Standard.

Microstructure evolution of 2014 aluminum alloy was studied by hot compression deformation at 410˚C to 470˚C and strain rates of 0.07 s −1 to 0.53 s −1 , to provide manufacturing references for aluminum plate. The deformation temperature and especially strain rate ranges were chosen very close to the actual processing condition. The results show that the stress-strain curves display a stable flow at the given deformation conditions, corresponding a dominant microstructure evolution behavior of dynamic recovery (DRV) and few dynamic recrystallization (DRX). After solution treated at 502˚C for 3 hours, quasi in-situ observation shows that static recrystallization (SRX) develop typical fine grains with several microns at grain boundaries, while static recovery (SRV) dominants the microstructure evolution during the soaking time, leading to a similar microstructure to that of the as-deformed. The average low angle grain boundaries (L AGBs) and high angle grain boundaries (H AGBs) display weak differences between as-deformed and solution treated specimens, which reveals a good thermal stability of microstructure for 2014 alloy. However, the deformation at the lower temperature has an obvious trend to induce SRX during solution soaking.
