“…Shi et al [ 66 ] quantitatively studied the twin boundary characters and derived an analytical model that displays an inversely proportional relationship between Σ3 twin boundary density and DRX grain size during the hot compression process of Ni80A superalloy. Quan et al [ 61 ] conducted the superimposed contour plot maps to uncover the relationships of twin density with grain size and stored energy varying with temperature and strain rate during the thermal deformation process of Nimonic 80A. Recently, Quan et al [ 121 ] proposed a new two-stage deformation method, i.e., prior cold deformation followed by thermal deformation, to improve the GBCD during the thermal deformation process of Nimonic 80A.…”

“…Based on the fundamental assumption in Pande’s model, Shi et al [ 66 ] derived an inversely proportional relationship between twin density and DRX grain size to quantitatively describe the evolution of twin boundary density during a thermal–plastic deformation process of a nickel-based alloy. Based on the work of Detrois et al, Quan et al [ 61 ] developed an improved twin density model related to stored energy and grain size to predict the twin density evolution during the thermal deformation process of Ni80A superalloy. In their work, the stored energy was further considered to be a function of average grain size, with the aim of relating the twin density to the underlying thermal deformation variables.…”

“…To obtain the desired GBCD during the twinning-related GBE of FCC materials, there is a great interest in uncovering the internal evolution mechanisms of microstructures under different TMP treatment and thermal deformation parameters [ 53 , 57 , 58 , 59 , 60 ]. Furthermore, based on the growth accident theory, some researchers have directed their attention towards crafting twinning-related kinetics models that are linked to processing parameters and microstructural parameters, including grain size, stored energy, etc., to predict the evolution of special twin boundaries [ 21 , 22 , 61 , 62 , 63 , 64 , 65 , 66 ]. These works help to achieve GBCD control during the twinning-related GBE of FCC materials.…”

Grain boundary engineering (GBE) is considered to be an attractive approach to microstructure control, which significantly enhances the grain-boundary-related properties of face-centered cubic (FCC) metals. During the twinning-related GBE, the microstructures are characterized as abundant special twin boundaries that sufficiently disrupt the connectivity of the random boundary network. However, controlling the grain boundary character distribution (GBCD) is an extremely difficult issue, as it strongly depends on diverse processing parameters. This article provides a comprehensive review of controlling GBCD during the twinning-related GBE of FCC materials. To commence, this review elaborates on the theory of twinning-related GBE, the microscopic mechanisms used in the optimization of GBCD, and the optimization objectives of GBCD. Aiming to achieve control over the GBCD, the influence of the initial microstructure, thermo-mechanical processing (TMP) routes, and thermal deformation parameters on the twinning-related microstructures and associated evolution mechanisms are discussed thoroughly. Especially, the development of twinning-related kinetics models for predicting the evolution of twin density is highlighted. Furthermore, this review addresses the applications of twinning-related GBE in enhancing the mechanical properties and corrosion resistance of FCC materials. Finally, future prospects in terms of controlling the GBCD during twinning-related GBE are proposed. This study will contribute to optimizing the GBCD and designing GBE routes for better grain-boundary-related properties in terms of FCC materials.

This study aims to explore the effect of deformation parameters on microstructure evolution during the new two-stage annealing method composed of an aging treatment (AT) and a cooling recrystallization annealing treatment (CRT). Firstly, the hot compressive tests with diverse deformation parameters were finished for an initial aged deformed GH4169 superalloy. Then, the same two-stage annealing method was designed and carried out for the deformed samples. The results show that the deformation parameters mainly affect the grain microstructure during CRT by influencing the content, distribution and morphology of the δ phase after deformation. The reason for this is that there is an equilibrium of the content of the δ phase and Nb atom. When the deformation temperature is high, the complete dissolution behavior of the δ phase nuclei promotes the dispersion distribution of the δ phase with rodlike and needle-like shapes during AT. Thus, the fine and heterogeneous microstructure is obtained after annealing because the recrystallization nucleation is enhanced in those dispersed δ phases during CRT. However, when the retained content of δ phase nuclei is high after deformation, the clusters of intragranular δ phases will form during AT, resulting in the pinning of the motion for dislocation. The elimination of the mixed grain microstructure is slowed down due to the low static recrystallization (SRX) nucleation rate within the deformed grain.
