The Orientation Dependence of the Rate of Grain Boundary Migration

Abstract

Very small recrystallized grains of a large variety of orientations were produced locally in lightly rolled high purity aluminum crystals. The rate of growth of these small grains varied greatly, depending on their relative orientation with respect to the matrix crystal. Grains with an orientation corresponding to a [111] rotation of about 40° showed by far the highest rate of growth. These results indicate that recrystallization textures developing in the spontaneous recrystallization of deformed single crystals can be accounted for by the orientation dependence of the rate of growth.

Conditions for Grain Boundary Bulging during Tempering of Lath Martensite in Ultra-low Carbon Steel

“…[5][6][7] For example, Titrov 7) showed experimental data on texture formation which demonstrates that the boundaries with misorientation angle in the range of 15-45°mi-grated faster than other boundaries in various FCC and BCC metals including Fe-3%Si alloy. In the case of the example in Fig.…”

Boundary Migration during Recrystallization of Heavily Deformed Pure Nickel

“…1 is not suitable for the description of such a stop-go type of movement [4]. Early observations of protrusions can be found in the classic work by Beck et al [5] on the recrystallization of high-purity aluminium. However, a theoretic model has only very recently been discussed by Martorano et al [6].…”

Relationship between ⟨111⟩ Rotation Recrystallization Mechanism and Slip Bands with Compressive Strains during Tensile Deformation in Aluminum Single Crystals

“…However they have not explained the mechanism of h111i rotation RGs. The latter ones standing by the theory of growth, for example by Barrett,21) Beck, Sperry and Hu, 22) Kohara, Parthasarathi and Beck, 23) Yoshida, Liebmann and Lücke, 24) and Senna and Lücke, 25) have asserted that h111i rotation RGs are formed by the easy growth of the RGs with approximately 40 h111i rotation relation to each adjoining deformed matrix (ADM).…”
