摘要
在高温形变后，把超低碳钢在７００～９２０℃之间保温，以此作为开轧温度（ＦＥＴ），测定钢的晶粒度、应力－应变曲线，并进行显微组织观察。试验的结果是在铁素体已热轧、退火后可得高塑性。
After high temperature deformation,ultra low carbon steel is held between 700￣920℃,being as the temperature for the first pass.Crystal grain size,stressstrain curve of the steel are determined and microstructures are analyzed.The test results show that ferrite hot rolled and annealed has high plasticity.
