Abstract
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.
