Hot Rolled

The effect of hot rolling temperature and reduction in ferrite region on the microstructure, texture and deep drawability of Ti-IF steel sheets were investigated. The results showed that after ferritic hot rolling and annealing, Ti-IF steel sheets developed uniform equiaxed ferrite grains and strong <111>//ND recrystallized fibers, the maximum r-value was 1.725 and good deep drawability was achieved. The deep drawability was improved with the decrease of ferritic hot rolling temperature, also enhanced with the increase of reduction in ferrite region. Texture analysis indicated that low hot rolling temperature and large reduction in ferrite region could increase the intensities of favorable {111}<112> and {554}<225> recrystallization textures and also reduce that of unfavorable {001}<110> recrystallization texture, therefore the r-value and deep drawability were enhanced.

Relief Effect

Effects of product shape and a planar-anisotropy on a square shell drawability were studied, using commercially pure aluminum sheet. Two phenomena were mainly considered to affect a forming limit: (a) the prevention of crack initiation at the corner of a punch by adjacent straight punch profile regions, (b) the metal flow in the flange region from the corner to the straight side, the “Strain Relief Effect,” which serves to decrease the deformation at the corner.

R Value

Correlation between the deep-drawability of commercially pure aluminum sheets and the r value is investigated in detail. First, sheets with various r values are specially made for this study, and the conditions for making extra high r-value sheets are clarified. Then, it is found from the deep-drawability test that the limiting drawing ratio has a positive though weak correlation with r value. The reasons are considered both from the standpoints of drawing resistance and fracture strength and attributed to the variations of the r value during working. As a result, finding a strain path to enhance the r value is considered to be a future problem in the improvement of deep-drawability.
