Comparison in the formability of the final sheets produced by the CCR and TCR processes. (a) Erichsen value as a function of thickness reduction in the second stage of the rolling process; the numbers in parentheses indicate the improvement of the formability with respect to the CCR. Erichsen value as a function of (b) average r-value and (c) planar r-value. Error bar indicates the standard deviation.
