The production mechanism of extensively sharp Goss orientation in HI-B material

The production mechanism of highly sharpened Goss orientation in HI-B material was investigated in a comparison with the conventional. Both materials involve multistage orientation selection processes during the secondary Goss grain evolution, notably, the nucleation stage and the later growth stage generate distinctive selections. In HI-B material, each selection process produces considerably different orientation and consequently very small tolerance of the deviation angle is allowed.
