金属材料经冷加工变形后,其晶体往往优先按某一方位排列,这种晶体取向的聚集现象被称为织构.织构不仅在冷加工变形后的金属材料中出现,而且在热变形、冷加工退火后,铸锭、沉积的金属膜中,以及岩石、纤维等天然产物中也经常存在. 由于织构的存在,往往引起金属材料各方向上的性能有差异,即各向异性.当材料进行二次加工成形过程中,会因此而变得困难.
After the cold deformation of metal materials, the crystal tends to be preferentially arranged in a certain orientation, this phenomenon of crystal orientation is called texture.Creation not only in the cold deformed metal materials appear, but also in the thermal deformation, cold working annealing After the ingot, deposited metal film, and rock, fiber and other natural products often exist.Because of the existence of the texture, often cause the performance of the metal material in all directions are different, namely, anisotropy.When the material for two Secondary processing and forming process, will therefore become difficult.
