Effects of caliber rolling on microstructure and room temperature .

The stress–strain curves obtained from tensile tests at room temperature were found to vary with the temperature employed in caliber rolling. Maximum tensile strength of 290 MPa and ductility of 13.5% were obtained upon caliber rolling at 300 °C as compared to 188 MPa and 15.2%, respectively, in the mill-rolled condition.
