EFFECTS OF RECRYSTALLIZATION TEXTURES ON THE PLASTIC STRAIN RATIO R AND DEEP-DRAWING PROPERTIES OF COLD ROLLED LOW-CARBON STEEL SHEETS CONTAINING TITANIUM

The effects of titanium 0.145-0.35% corresponding to the ratio Ti/(C+N)varied from 2.9 to 10.1 on the recrystallization textures of cold rolled low-carbonsteel sheets have been investigated in comparison with the plastic strain ratio Rand deep-drawing properties. For the ratio Ti/(C+N)>4, the main texture com-ponent of (111) 112] is beneficial to the deep-drawing ability; for the ratio Ti/(C+N)<4, that of (100) 011] is detrimental. It would appear that the deep-drawingproperties were substantially determined by the type and degree of the recrystal-lization textures, but not by their erystalline shape. The influence of fine precipi-tates of TiC phase on the recrystallization texture has been discussed.
