织构和极图多晶材料在结晶、加工和退火时,由于变形和再结晶等效应使得材料内部晶粒的位向沿着加工等方向形成一种有规则的择尤分布现象,称为织构。由于织构的存在,使得材料在力学性能和物理性能上显示出各向异性。在金属材料生产中,有时为了提高某些性能,要求集中的织构,能显示出强烈的各向异性,如晶粒取向冷轧硅钢片、立方织构Fe—Ni软磁合金等:有时为了满足另一些性能要求,又需要减少甚至消除织构,如小取向冷轧硅钢片要求减少织构,一些深冲
Texture and pole figure Polycrystalline material in the crystallization, processing and annealing, due to deformation and recrystallization and other effects make the material within the grain direction along the processing direction to form a regular selective especially distribution phenomenon, known as weaving Structure. Due to the existence of texture, the material shows anisotropy in mechanical properties and physical properties. In the production of metal materials, sometimes in order to improve some of the performance, require centralized texture, can show strong anisotropy, such as grain-oriented cold-rolled silicon steel, cubic texture Fe-Ni soft magnetic alloy: sometimes Meet other performance requirements, but also need to reduce or even eliminate the texture, such as small-oriented cold-rolled silicon steel sheet to reduce the texture, some deep red
