摘要：
Ultrafine grained steels with different carbon contents were produced through warm caliber rolling and evaluated for their stress-strain behavior along with the reduction in area. It was found that the reduction in area-tensile strength balance is far better than the conventional ferrite + pearlite steels and even superior to bainitic steels for all materials tested in the present study.
