at 900 〜 1 100℃ has been carried out by thermal test machine. Results show that with decreasing temperature
increasing strain rate and deformation extent
the deformation resistance of ultra-low carbon steel increases. And the math model of deformation resistance of the ultra-low carbon steel is established by Origin software with multi-component non-linear regression
