“…Microstructures of AISI 4340 for all deformation temperatures and two limiting values of deformation rates are in Figure 15 (ϕ' = 10 s −1 ) and Figure 16 (ϕ' = 0.001 s −1 ). The deformation temperature has a significant influence on the grain size [46]. In both shown cases of strain rates, grain size increases in proportion to temperature.…”

The paper is focused on investigation of the high-strength AISI 4340 steel at various temperature and deformation conditions. The article is divided into two specific analyses. The first is to examine the dilatation behavior of the steel at eight different cooling rates, namely, 100, 10, 5, 1, 0.5, 0.1, 0.05 and 0.01 °C·s−1. The mapping of the phase transformations due to varying cooling rates from the austenitizing temperature of 850 °C allows the construction of the CCT diagram for a given high-strength steel. These dilatation curves were also compared with the metallography of the selected samples for the proper construction of the CCT diagram. A further analysis of the high temperature deformation of high strength steel AISI 4340 was performed in the range of temperature 900–1200 °C, and the strain rate was in the range from 0.001 to 10 s−1 with maximum value of the true strain 0.9. Changes in the microstructure were observed using light optical microscopy (LOM). The effect of hot deformation temperature on true stress, peak stress and true strain was investigated. The hardness of all deformed samples, depending on the temperature, the deformation rate and the peak stress σp overall together related with hardness, has also been evaluated.

“…Dilatometer DIL805A/D is a laboratory device used to measure and record dilatation curves or to measure hot deformation resistance. Therefore, it is well designed for the physical modelling of hot forming processes [19][20][21][22]. An experimental sample of the prescribed shape and dimensions of ø 5 × 10 mm 2 from the as hot rolled condition is inserted into the working chamber between two ceramic jaws.…”

The paper mainly focuses on calculating and comparing a mathematical model of the deformation behaviour at high temperatures. Analysis of the high-temperature plastic behaviour of lean medium-manganese steel 0.2C3Mn1.5Si was carried out in the temperature range of 900-1200 • C and the deformation rate in the range of 0.01-10 s −1 to the maximum value of the true strain 0.8. Microstructural changes were observed using light optical microscopy (LOM) and scanning electron microscopy (SEM). The effect of hot deformation temperature on true stress, peak stress, and the true strain was evaluated using the flow curves. Based on these results, transformations in steel were discussed from the dynamic recovery and recrystallisation point of view. Furthermore, a present model, taking into account the Zener-Hollomon parameter, was applied to predict the true stress and strain over a wide range of temperatures and strain rates. Using constitutive equations, material parameters and activation energy for the investigated steel could be derived. Results demonstrate the use of the model for lean medium-Mn quenching and partitioning steel (Q&P) compositions in hot deformation applications with acceptable accuracy.

“…Besides, the introduction of an exothermic addition increases the deposition rate [ 49 ], improves the morphology of the weld bead [ 51 , 119 ], arc process efficiency [ 119 ] and the hardfacing process stability [ 120 ]. Тrembach et al [ 49 ] determined that the introduction of exothermic addition (CuO–Al) of to the core filler had a significant effect on such indicators of the weld bead morphology, microstructure and mechanical properties [ 87 , [121] , [122] , [123] ].…”
