冷延鋼板の再結晶集合組織におよぼす炭素の影響

抄録

The effects of carbon content below 46 ppm on the recrystallization texture were examined with a decarburized Al-killed steel of commercial purity. The carbon contents in the steel were varied by carburizing at 700°C before cold rolling or at 420°C after cold rolling, and then their recrystallization textures resulting from both cases were compared.
The carbon content during annealing influenced the recrystallization textures when it ranged between zero and 20 ppm. The increase in the carbon content increased the amount of {110} components and decreased that of {100} components. This effect was believed to be caused by the carbon in solution. The carbon content during cold rolling was also found to have an influence on the recrystallization texture, when it exceeded 20 ppm. The increase in the carbon decreased the amount of {111} components and increased that of {110} components. This effect was thought to be due to the presence of iron carbide particles during cold rolling.
