主 题:Aluminum killed low-carbon steel sheet Recrystallization Annealing Vickers hardness Texture
摘 要:Aluminum killed low-carbon steel sheets were cold rolled at different reduction ratios and annealed using different temperatures and holding *** Vickers hardness was *** results show that when cold rolling reduction ratios increase from 40% to 81%,recrystallization temperatures decrease from 602℃ to 572℃ during 4hisochronal annealing,as well recrystallization holding time decreases from 117 min to 5min during isothermal annealing at 610℃.All recrystallization temperatures and holding time can be calculated using the annealing experiment *** was examined through electron backscattered diffraction(EBSD).The results show that as rolling direction preferentially grows,equiaxed grains grow into cake-type during ***-type grains are more beneficial to obtaining ideal〈111〉//ND(normal direcrtion)orientation texture.{111}orientation grains nucleate and grow up *** grains of{111}〈110〉orientations grow into new recrystallization grains of{111}〈123〉and{111}〈112〉during *** formation can be explained by directional nucleation.
