Effect of Carbide Size, Cold Reduction and Heating Rate in Annealing on Deep-Drawability of Low-Carbon,
Capped Cold-Rolled Steel Sheet
Keyword(s):
The effects of carbide size prior to cold rolling, cold reduction and heating rate in annealing on r¯-value, and texture of cold-rolled steel sheets were investigated. The main results obtained were as follows: (1) When the carbide size prior to cold rolling is large, r¯-value can be improved with a faster heating rate in annealing. (2) Moreover, the cold reduction of peak r¯-value shifts to the higher cold reduction side, and r¯-value tends to increase with cold reduction up to 90%. These phenomena are thought to be based on the delay in dissolution of carbide at the initial state of recrystallization, the change in recrystallization temperature and the preferred nucleation.
