“…In figure 12(f), we also observed that the growth of TBs is substantially facilitated using an initial microstructure with a high fraction of HAGB. Lastly, we discuss the results of the present simulations in comparison to recent experimental observations of TB development in nanocrystalline materials [45]. Julie et al [45] investigated the effect of grain size on texture formation during annealing using electrodeposited nickel samples with different average grain sizes, ranging from 20 nm to 200 nm.…”

Julie et al [45] investigated the effect of grain size on texture formation during annealing using electrodeposited nickel samples with different average grain sizes, ranging from 20 nm to 200 nm. It is observed that the fraction of TBs in the final microstructure increases as the average grain size in the initial microstructure decreases.…”

“…The main difference between cases 2b and 2c is the fraction of GB types in the initial condition. Unfortunately, however, since the initial fractions of GB types are not reported in [45], a conclusive discussion cannot be made at this time.…”

“…The control of texture, crucial for determining the mechanical and electrical properties of polycrystalline materials, has been a subject of sustained interest [42][43][44]. For instance, recently Julie et al [45] explored the impact of grain size on texture formation during annealing using electro-deposited nickel samples with varying average grain sizes in the initial microstructures. In the similar vein, in this work we will focus on microstructures with different fractions of low-angle grain boundaries (LAGBs) and high-angle grain boundaries (HAGBs).…”

This paper investigates the statistical behavior of a two-dimensional grain microstructure during grain growth under anisotropic grain boundary characters. We employ the threshold- dynamics method, which allows for unparalleled computational speed, to simulate the full- field curvature motion of grain boundaries in a large polycrystal ensemble. Two sets of numerical experiments are performed to explore the effect of grain boundary anisotropy on the evolution of microstructure features. In the first experiment, we focus on abnormal grain growth and find that grain boundary anisotropy introduces a statistical preference for certain grain orientations. This leads to changes in the overall grain size distribution from the isotropic case. In the second experiment, we examine the texture development and growth of twin grain boundaries at different initial microstructures. We find that both phenomena are more pronounced when the initial microstructure has a dominant fraction of high-angle grain boundaries. Our results suggest effective grain boundary engineering strategies for improving material properties.

“…As shown in Table 1 , most studied nanocrystalline materials are produced via thin-film deposition: sputter deposition [ 31 , 32 , 72 , 78 , 79 ], pulsed deposition [ 35 , 80 ], electrodeposition [ 34 , 40 ], or gas deposition [ 44 , 45 , 81 ]. Deposited thin films result in high chemical purity materials as they are produced under a clean environment and they typically present columnar grains [ 82 , 83 ].…”

Thermal and Radiation Stability in Nanocrystalline Cu

Nanocrystalline metals have presented intriguing possibilities for use in radiation environments due to their high grain boundary volume, serving as enhanced irradiation-induced defect sinks. Their promise has been lessened due to the propensity for nanocrystalline metals to suffer deleterious grain growth from combinations of irradiation and/or elevated homologous temperature. While approaches for stabilizing such materials against grain growth are the subject of current research, there is still a lack of central knowledge on the irradiation–grain boundary interactions in pure metals despite many studies on the same. Due to the breadth of available reports, we have critically reviewed studies on irradiation and thermal stability in pure, nanocrystalline copper (Cu) as a model FCC material, and on a few dilute Cu-based alloys. Our study has shown that, viewed collectively, there are large differences in interpretation of irradiation–grain boundary interactions, primarily due to a wide range of irradiation environments and variability in materials processing. We discuss the sources of these differences and analyses herein. Then, with the goal of gaining a more overarching mechanistic understanding of grain size stability in pure materials under irradiation, we provide several key recommendations for making meaningful evaluations across materials with different processing and under variable irradiation conditions.
