Texture-tensile properties correlation of 304 austenitic stainless steel rolled with the change in rolling direction

Abstract

Rolling, at elevated temperature, with a change in the rolling direction (RD) have been conducted on 304 austenitic stainless steel. Two different sequences of change in RD, after each pass, have been followed viz., change in RD by 90°; designated as cross rolling (CR) and change in RD by 180°; designated as reverse rolling (RR). Effect of this change in RD on texture and tensile properties has been studied through Electron backscattered diffraction (EBSD) and uniaxial tensile test, respectively. In addition, tensile tests have been performed to study the anisotropy in tensile properties. The result shows a significant effect on the texture component formation. RR develops strong Cu and S components whereas CR forms strong Brass component. However, both the rolling sequence produces moderate Goss orientation. The observed tensile properties are correlated with the texture developed by both the processes.
