Study on the Deformation Resistance of 12Cr2Mo1R Steel

通过热模拟试验,研究了变形温度、变形速率、变形程度对12Cr2Mo1R钢变形抗力的影响,结果表明,在较低的温度和较高的变形速率下,12Cr2Mo1R钢变形抗力增加显著;在同一下变形程度下,随温度的升高,变形抗力降低。变形温度为800℃、变形速率为15 s-1时,变形抗力最大值为290 MPa;变形温度为1 050℃、变形速率为1 s-1,变形抗力最小值为110 MPa。

Based on the thermal simulation test, the influence of deformation temperature, deformation rate and deformation degree on the deformation resistance of 12Cr2Mo1R steel was studied. The results showed that under lower temperature and higher deformation rate, the deformation resistance of 12Cr2Mo1R steel increased significantly; under the same deformation degree, with the increasing of temperature, the deformation resistance decreased. The deformation temperature is 800 ℃ and the deformation rate is 15 s^-1, the maximum value of deformation resistance is 290 MPa; the deformation temperature is 1 050 ℃ and the deformation rate is 1 s^-1, the minimum value of deformation resistance is 110 MPa.
