摘要

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 recrystailized 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.
