切削加工是一种在工业Fe-4%Si合金中施加大剪切应变（γ ε 2）的变形技术。变形<111>后的显微组织中产生了部分织构和{110}纤维织构，这是体心立方金属在简单剪切变形中所期望的。使用类似于商业轧制工艺中的退火时间表，样品保留变形织构，与连续型再结晶机制一致。细晶退火样品揭示了两种不同的部分纤维取向，其中之一成为主导织构，以下的高温生长处理。讨论了机械加工过程中织构演变的机理及其对织构控制的影响。
Machining is used as a deformation technique to impose large shear strains (γ ∼ 2) in a commercial Fe-4%Si alloy. The partial <111> and {110} – fiber texture components are generated throughout the as-deformed microstructure, which is expected of BCC metals deformed in simple shear. Using an annealing schedule similar to that in the commercial rolling process, samples retain the deformation texture, consistent with a continuous-type recrystallization mechanism. Fine-grained annealed samples reveal two different partial fiber orientations, one of which becomes the dominate texture, following the high-temperature growth treatment. The mechanisms of texture evolution and implications for texture control in the machining-based process are discussed.
