Deep drawability of electro-deposited pure iron having an extremely sharp 〈111〉//ND texture

Abstract

Electro-deposited pure iron having an extremely sharp 〈111〉//ND fiber texture has extraordinarily excellent deep drawability. The relaxed constraints models based on Taylor theory cannot predict such high r-values. This excellent deep drawability seems to arise not only from the sharp 〈111〉//ND texture but also significantly from the specific morphology of the microstructure, i.e. needle-shaped fine grains elongated in the normal direction. © 2008 ISIJ.
