The microstructure and texture in pure nickel were investigated during multi-step cross cold rolling (CCR) and subsequent annealing. It was found that the deformation texture in the CCR nickel was dominated by Brass and rotated Brass about normal direction (ND) (Bs^ND) texture components, along with marginal cube textures. The resulted deformation textures had a significant effect on the recrystallization behavior. Annealing of the CCR nickel at 550°C for 1 h led to the formation of dominant <012> // ND fiber accompanied by minor rotated cube textures, rather than strong cube texture. Increasing the annealing temperature up to 800°C resulted in further enhancement of <012> // ND fiber textures. The possible reasons for recrystallization behavior in annealed CCR sample were discussed based on in-situ annealing experiments from two aspects of oriented nucleation and oriented growth theories.

交叉冷轧和退火对纯镍组织和织构的影响

在多步交叉冷轧（CCR）和随后的退火过程中，研究了纯镍的显微组织和织构。发现CCR镍中的变形织构主要由黄铜引起，并且黄铜沿法线方向（ND）旋转（Bs ^ND）纹理成分，以及边际立方体纹理。产生的变形织构对再结晶行为具有显着影响。CCR镍在550°C退火1 h导致形成主要的<012> // ND纤维，并伴有较小的旋转立方纹理，而不是强固的立方纹理。将退火温度提高到800°C会进一步增强<012> // ND纤维的织构。从定向成核和定向生长两个方面出发，基于原位退火实验，探讨了退火后的CCR样品再结晶行为的可能原因。
