摘要
在铁酸盐范围的极端低的碳钢的热变丑实验在一个热模拟器被执行以便在低温度在铁酸盐范围研究极端低的碳钢的热变丑行为。结果证明流动应力上的变丑参数的影响对在奥氏体的变丑的那些不同。变丑特征参数在铁酸盐区域为极端低的碳钢被计算。为在在低温度的以铁酸盐为主要成的变丑的极端低的碳钢的流动压力方程被获得。
The hot deformation experiments of ultra-low carbon steel in ferrite range were carried out in a hot simulator in order to research hot deformation behaviors of ultra-low carbon steel in ferrite range at low temperature. The results show that the influences of deformation parameters on flow stress are different to those in austenitic deformation. The deformation characteristic parameters were calculated for ultra-low carbon steel in ferrite region. The flow stress equation for ultra-low carbon steel in ferritic deformation at low temperature was obtained.
