Among the severe plastic deformation processing (SPD) of materials, high-pressure torsion (HPT) is known to induce considerable amounts of plastic strain and crucial grain refinement up to the nanometer scale. There have been several reviews on the mechanical properties and/or microstructure correlations of SPD-processed materials published during the last two decades. By contrast, a review on the crystallographic texture evolution during HPT processing is not at present available. Consequently, this work was undertaken to review the texture evolution in Face-Centered Cubic (FCC), Body-Centered Cubic (BCC) and Hexagonal Close-Packed (HCP) crystal structure materials processed exclusively by HPT with a special emphasis on the influence of many intrinsic and extrinsic factors such as the imposed strain, the deformation temperature and the alloying elements.

在材料的严重塑性变形加工 (SPD) 中，已知高压扭转 (HPT) 会引起相当大的塑性应变和关键的纳米级晶粒细化。在过去的 20 年里，已经发表了几篇关于 SPD 处理材料的机械性能和/或微观结构相关性的评论。相比之下，目前还没有关于 HPT 加工过程中晶体结构演变的综述。因此，这项工作是为了回顾面心立方 (FCC)、体心立方 (BCC) 和六角密堆积 (HCP) 晶体结构材料的纹理演变，专门由 HPT 处理，特别强调了许多内在和外在因素，例如施加的应变，
