The effect of finishing temperature on the texture and structure of hot rolled 1 pct Si steel

Abstract

An investigation has been made of the effect of finishing temperature on the texture and structure of a commercial, 1 pct Si steel. Finishing temperatures in the range of 1610° to 1280°F were found to produce three types of rolling texture. Texture I, which was close to random, occurred with finishing temperatures in the range 1610° to 1580°F; texture II, which consisted of a strong [011] fiber texture in the rolling direction, occurred with increasing intensity in the range 1580° to 1430°F, while below 1430°F texture III was developed and consisted of the [011] fiber texture together with a strong 〈111〉 fiber texture, with the fiber axis parallel with the sheet normal. It was found that these three types of texture could be related to microstructures which ranged from equiaxed at 1610°F through a duplex recrystallized structure at intermediate temperatures to an elongated “cold worked” structure at the lowest finishing temperature.
