Texture Memory Effect in Heavily Cold-Rolled Ni₃Al Single Crystals

Abstract

Abstract. The paper presented the texture evolution during primary recrystallization and following grain growth in the heavily cold-rolled Ni 3 Al single crystals. It turned out that the texture evolution occurred in the two stages. First, primary recrystallization caused the drastic change of the as-rolled texture. Then, as grain growth proceeded, the texture returned to the same one as the as-rolled textures. This texture return can be designated as Texture memory effect. The mechanism of the texture memory effect was discussed based on the analysis of the orientation relationship between the as-rolled and the primary recrystallization textures.

Anisotropic Behaviours of Lpbf Hastelloy X Under Slow Strain Rate Tensile Testing at Elevated Temperature

“…GOSS texture with elongated grain structure and high dislocation density in LPBF HX show similarity with rolled materials [74][75][76]. The high dislocation density in rolled materials promotes dynamic recrystallization when heat treatment is applied, and the dynamic recrystallization further leads to texture evolution, specifically forming Goss component.…”

Texture and Ductility of Ni₃Al Foils

“…The X-ray texture measurements revealed an interesting two-stage texture evolution in the recrystallization and the subsequent grain growth [16], as shown in Fig. 2 for two Ni 3 Al foils with the Goss texture (a-c) [16] and the dual Brass texture (d-f) [17]. In both cases, the textures were disintegrated after the recrystallization, consisting of several texture components that were different from the cold-rolled textures (Fig.…”

“…Finally, in case of the Goss-textured foil, almost all the grains were determined to have the Goss orientation at the average grain size of 70 µm [12]. In case of the dual-Brass-textured foil, each band had a single Brass texture, similar to the cold-rolled state [17].…”

Recrystallization Textures in Heavily Cold-Rolled Ni₃Al Based Single Crystals

“…In the single-phase Ni 3 Al, we've found a very interesting phenomenon on the texture evolution during the recrystallization and grain growth, as follows subsequently heat-treated at 873K/0.5h after the cold rolling, and (c) at 1273K/0.5h. [15][16][17]. First, the cold-rolled foil had a strong {110} texture, as shown in Fig.…”
