Effect of Manganese Content on the Development of (111) Transformation Texture in 0.03 Ti-Bearing Extra-low Carbon Steel Sheets

摘要

The aim of the present study was to find a new approach to obtaining high-strength steel sheets with better press formability than of Al-Padded low carbon multi-phase steels. The results showed that the Manganese addition enhance the development of transformation structure. (111) transformation texture develops in 1.0% and even in 02% Mn steels. The changes in hardness, microstructure, and texture are examined through thickness, and it is found that the intemediate transformation products were more suitable than martensite for developing (111) transformation texture, and that addition of less than 25 ppm C was sufficient to obtain high-strengih steel sheets with good deep drawability.
