analysis during hot extrusion and cold rolling process[9, 10] were carried out in order to explore the strengthening mechanism associated with texture. It was revealed that the matrix plastic deformation... and revealed that the final cold rolling textures was rather alike[19]. The reason could be attributed to the weak textures produced during hot extrusion process. 4 CONCLUSIONS Finite element......

on a d 270 mm two-high rolling mill (preheated at 343-363 K). During the hot rolling processing the sheets should be preheated or intermediate annealed at 573, 623, and 673 K respectively in a muffle... for the thin sheets. The surface temperatures of sheets measured by radiation thermometer were about within 353-423 K before entering into roll gap. The hot rolling was carried out at a velocity of 3, 6 and 16 m......
