In automated equipment for orientation research, the intensity for drawing up the pole figure is measured in detail. The present research shows that the accurate pole figure can be drawn up without measuring concretely the intensity. For directional Si steel sheet the measuring step may be 4～5 degrees. In this paper the experimental equation for defo-cusing correction was derived from the experimental data in different specimens with random orientation.展开更多

A {0001} fibretexture an0d a weak {1210} <1010> texture were found after 35% cold rolling at room temlierature. The activation process of slip systems was discussed concerning formation of the rolling texture. Because of the low ductility of the material it is believed that the grains were deformed by simple glide suggested by Sachs.展开更多
