“…In the case of the BM specimen, these cracks propagate along random HAGBs toward the J0 junction ( Figure 19 a) or other random HAGBs ( Figure 19 b), while the low-ΣCSL boundaries formed in the GBE specimen hinder inter-crack penetration ( Figure 19 c,d), thereby retarding crack propagation. Guan et al [ 131 ] also conducted tension–tension fatigue tests on non-GBE and GBE specimens of this alloy. They suggested that intergranular fatigue cracking can be effectively suppressed through the application of an appropriate GBE treatment, thereby improving the low-cycle fatigue life 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.

Face centered cubic (FCC) metals are widely used in the field of structural materials due to their excellent mechanical properties, and their fatigue behaviors have always been a focus of attention. In this work, 1060 aluminum alloy with different processing states and copper were selected to study the high cycle fatigue performance at room temperature and high temperature. The fracture morphology and dislocation evolution were characterized through characterization methods such as scanning electron microscope (SEM) and transmission electron microscope (TEM). Based on the research, the main movement mode of dislocations (plane slip or wavy slip) is influenced by stacking fault energy (SFE), which further has a significant impact on fatigue performance. When the SFE of the FCC metal is higher, wavy slip dominates and the material is sensitive to temperature changes; on the contrary, during cyclic loadings, metal with lower SFE is dominated by plane slip, due to the reversibility of plane slip, the damage to the material with low SFE under fatigue loading is more uniform.This article is protected by copyright.
