| 摘 要： | 通过SEM、EBSD和拉伸试验研究了温轧温度对中碳Cr-Mo钢组织演变和力学性能的影响。结果表明:较高温轧温度有利于Cr-Mo钢组织的均匀分布,当轧制温度从500 ℃增加到600 ℃时,铁素体晶粒尺寸由0.424 μm增加到0.490 μm,晶粒尺寸差别不断减小,屈服强度由1380 MPa下降至1062 MPa,在550 ℃轧制试验钢的塑性最好,强塑积最高,为5816 MPa·%。

| Abstract: | Effect of warm rolling temperature on microstructure evolution and mechanical properties of medium carbon Cr-Mo steel was investigated by means of scanning electron microscope(SEM), electron backscattered diffraction(EBSD) and tensile tests. The results show that the increase of rolling temperature has a favorable effect on the uniform distribution of the microstructure. When the rolling temperature increases from 500 ℃ to 600 ℃, the grain size of ferrite increases from 0.424 μm to 0.490 μm, the grain size difference decreases, and the yield strength decreases from 1380 MPa to 1062 MPa. The experimental steel rolled at 550 ℃ has the best plasticity and the highest plastic product reaches 5816 MPa·%. |
