Deep Drawability of Electro-deposited Pure Iron Having an Extremely Sharp ‹111›//ND Texture

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 text...

Zusammenfassung: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.
