“…As there are no changes in the normalized work hardening rate of regime D, and lines in strains greater than 0.9 strain (end of regime C) overlap, regime D is shown until the strain 1.2. In regime B, unlike other regimes, the strain hardening rate is ascending and relatively constant, which has not occurred with such strength in IN625, MP35N, and IN X-750 superalloys [ 14 , 23 , 29 ] under simple pressure. For further investigation of the curve in Figure 10 b, Figure 11 shows an overview of macro etched samples after PSC testing.…”

“…This creates an inhomogeneous deformation through shear bands. In the curve of Figure 10 b, four separate regimes of normalized work hardening rates for the IN625, MP35N, and IN X-750 superalloys with low SFE values [ 14 , 23 , 29 ] are prominent. As there are no changes in the normalized work hardening rate of regime D, and lines in strains greater than 0.9 strain (end of regime C) overlap, regime D is shown until the strain 1.2.…”

“…The driving forces of work hardening of Inconel alloys, which is non-linear [ 51 , 52 ], are the dislocation glide and twinning mechanisms. As a result, plastic-deformation energy is converted into heat, the value of which and possible dissipation depends on the strain rate.…”

The paper is devoted to highlighting the potential application of the quantitative imaging technique through results associated with work hardening, strain rate and heat generated during elastic and plastic deformation. The aim of the research presented in this article is to determine the relationship between deformation in the uniaxial tensile test of samples made of 1-mm-thick nickel-based superalloys and their change in temperature during deformation. The relationship between yield stress and the Taylor–Quinney coefficient and their change with the strain rate were determined. The research material was 1-mm-thick sheets of three grades of Inconel alloys: 625 HX and 718. The Aramis (GOM GmbH, a company of the ZEISS Group) measurement system and high-sensitivity infrared thermal imaging camera were used for the tests. The uniaxial tensile tests were carried out at three different strain rates. A clear tendency to increase the sample temperature with an increase in the strain rate was observed. This conclusion applies to all materials and directions of sample cutting investigated with respect to the sheet-rolling direction. An almost linear correlation was found between the percent strain and the value of the maximum surface temperature of the specimens. The method used is helpful in assessing the extent of homogeneity of the strain and the material effort during its deformation based on the measurement of the surface temperature.

“…In addition, SRO is also a possible phenomenon that occurs during the high temperature deformation of AL6XN ASS, which will make a contribution to the work hardening. It has been indicated in many researches that SRO can contribute to the special mechanical properties of alloys, such as working hardening behavior, planar slip structure of dislocation and serrated flow in stress-strain curve [17][18][19][20][21]. At higher temperatures, cyclic hardening disappears, especially at 600 °C, implying that the dynamic recovery may play an increasingly important role in fatigue deformation.…”

By the combination of transmission electron microscope, neutron diffraction and small-angle neutron scattering methods, mechanical fatigue behavior of AL6XN austenitic stainless steel was investigated in the temperature range of 400-600 °C. At 400 °C, in addition to the occurrence of dynamic strain aging, the formation of short-range order was evidenced from the forbidden electron diffraction spot of 1/3 {422} in face-centered cubic (fcc) structure viewed down [111] zone axis, which facilitate the planar slip mode of dislocation and result in the work hardening during the fatigue deformation. The fatigue damage is mainly dominated by the accumulation of planar slip band and the interaction among various slip systems. With increasing temperature, precipitates of chi phase, Laves phase and sigma phase were formed during the fatigue tests at 500 and 600 °C. An increase in precipitation content at 600 °C has also been confirmed by both scanning electron microscope and small-angle neutron scattering analysis. The dislocation pileup originating from the uncoordinated deformation between precipitate and austenitic matrix is an important fatigue damage leading to crack. The continuous cycle softening behavior was also observed on the fatigue curve at 600 °C, which is considered to be caused by dynamic recovery.
