抄録

Texture evolution by grain growth in the presence of MnS and AlN precipitates in 3%Si-Fe alloy processed by Taguchi’s method, was investigated by X-ray diffraction and back Laue diffraction. Main findings obtained are as follows:<BR>(1) With higher cold reduction, sharpness of Goss secondary texture increases, however, fine grain areas with no Goss orientation are also evolved. The evolution of the sharper Goss texture is considered to be due to an increase in frequency of Σ9 type grain boundaries in relation to an ideal Goss orientation in the primary matrix by higher cold reduction, and the occurrence of the fine grain area is due to the decrease in the Goss nucleus grains in the primary matrix.<BR>(2) The texture of the above mentioned fine grain area is mainly {334}, while the major texture before grain growth is {113}.<BR>The mechanism of the texture evolution in the fine grain area is explained by the specific grain boundary migration characteristics in the weaker inhibitor intensity, namely, the texture evolved has closer relationship with the product of the intensity of its own and the frequency of the grains in Σ9 orientation relationship in the primary matrix.
