    Notes: The local-area analyses of the primary recrystallization sheets were carried out inFe-3%Si to explain the reason why only Goss appears during the secondary recrystallization. It wasfound in the present study that Goss grains have the higher Σ9 frequency in their nearest neighborsthan {311}〈011〉 grains, both of which were attached to the neighbors having the texture with highΣ9 frequency to the texture of the matrix. Another analysis showed that Σ1 and Σ3 frequencies werehigher around {311}〈011〉 grains than around Goss. It is concluded that Goss grains possess thesatisfactory criteria to be the secondary recrystallization nuclei from the following viewpoints ofhigh Σ9 frequency and low Σ1 and Σ3 frequencies

    Notes: Recrystallization of cold rolled {211}〈011〉 single crystal of 3.5%Si-Fe were investigated by electron back-scattered pattern (EBSP) technique in order to clarify the formation of {h,1,1}〈1/h, 1, 2〉 fiber in recrystallization texture of steel with high cold rolling reduction. In the cold rolled sample, there exist shearbandlike substructures characterized by the orientation fluctuation with single 〈011〉 axis whereas their orientations are almost kept to the original orientation {211}〈011〉 which belongs to a-fiber (RD//〈110〉 fiber). In the recovery stage, the orientation fluctuations are enhanced and include fluctuations with another 〈011〉 axis. That is the fluctuations in recovery stage are not characterized by rotation relationship with single 〈011〉 axis. The recrystallization texture includes {100}〈012〉 and {411}〈148〉 as major orientations in {h,1,1}〈1/h, 1, 2〉 fiber. Furthermore, there exists clear orientation relationship characterized by multiple rotations with 〈011〉 axes between the recrystallization orientations and the original one. Actually, orientations characterized by rotational relationships with 〈211〉 (=[110]+[101]) axis and 〈111〉 (=[110]+[101]+[011]) were observed. These results suggest that recrystallization from a-fiber is occurred as a result of the final enhanced stage of the fluctuations characterized by multiple rotations with 〈011〉 axes

    Notes: Heavily cold rolled BCC steel has been indicated to generate {411}〈148〉 recrystallisation texture and its family orientations which might be represented as {h,1,1}〈1/h,1,2〉. As a-fibre structure, or RD//〈011〉 texture is significantly developed during the cold rolling, it is naturally speculated to be the recrystallisation site of {h,1,1}〈1/h,1,2〉 fibre. The present paper prompts to demonstrate the recrystallisation procedure by utilising EBSP-OIM analysis. The first demonstrationwas carried out with OIM analysis on partially recrystallised cold rolled steel. At the stage of 50% recrystallisation, only ND//〈111〉 texture has appeared for the recrystallised area. {100}〈011〉 - {211}〈011〉 a-fibre remains as deformed structure, and several {h,1,1}〈1/h,1,2〉 grains could be found at the grain boundaries. Therefore, a bi-crystal of {100}〈011〉 was employed to simulate theirregular deformation at the grain boundary. After cold rolling, a warp toward the grain boundary was observed. Although the interior of the {100}〈011〉 single crystal was hardly recrystallised, sharp {411}〈148〉 texture was created along the grain boundary. In order to confirm the phenomenon, another experiment was carried out that a cold rolled {100}〈011〉 single crystal was bent along the rolling direction and annealed. Very sharp {411}〈148〉 recrystallisation texture was formed again at the bent perimeter. These experimental results lead us to conclude that the irregular strain was sufficiently piled at the grain boundary after the heavy deformation and generates {h,1,1}〈1/h,1,2〉 texture. On {100} pole figures, the recrystallisation textures were equivalently scattered around three 〈100〉 poles, therefore the rotation relationship around 〈111〉 axes with the original orientation was suggested
