Abstract

Texture evolution by grain growth in the presence of MnS or MnS and AIN precipitates in Fe−3% Si alloy was investigated by X-ray diffraction (vector method) and ECP (selected area electron channelling pattern). Texture evolved by grain growth varied with the intensity of the inhibitors in the following manner: when an inhibitor intensity is higher than a critical value, the orientation N having the highest ICΣi value in the matrix becomes major orientation after grain growth. Here the ICΣi value denotes an intensity of orientations with Σi type coincidence orientation relationship with a given orientation N (except Σ1 and Σ3 type coincidence orientations). When an inhibitor intensity is weaker than the critical value, the orientation (N) having the highest PCNΣi value in the matrix becomes major orientation after grain growth. Here the PCNΣi value denotes an product of a intensity of the given orientation (IN) and the ICΣi value. With an weaker inhibitor level, IN being more dominant and with a stronger inhititor level, ICΣi being more dominant under the same PCNΣi value. The inhibitor effect of PCNΣi1 value increases with increasing in the inhibitor intensity, where PCNΣ1 is a product of the intensity of the given orientation (IN)
