Interstitial free steel: Influence of α-phase hot-rolling and cold-rolling reduction to obtain extra-deep drawing quality

This paper shows the drawing properties of Ti-bearing interstitial free steel. The study was carried out on the basis of microstructure, mechanical properties and texture using X-ray diffraction techniques and orientation distribution function (ODF) analysis. The results obtained prove the influence of each stage of processing to achieve extra-deep drawing quality (EDDQ), focusing our attention on hot-rolling and cold-rolling reduction. It is demonstrated that the optimum cold-rolling reduction increases to 90% for both rm and Δr coefficients.
