摘　　要：通过热模拟试验机对超低碳钢M21(%:0.003C、0.045Al、0.06Ti、0.002 7N、0.000 2 B)Φ8 mm×12mm圆柱体试样在900～1100℃以5～50 s^(-1)变形速率进行0～80%压缩试验。结果表明,随温度降低、变形速率提高和变形程度增加,超低碳钢变形抗力增加。并借助Origin软件通过多元非线性回归建立了该超低碳钢变形抗力的数学模型,拟合精度较高。Hot compressive test of Ф8 mm × 12 mm cylinder test specimen of ultra-low carbon steel M21 （% ： 0. 003C, 0. 045A1, 0. 06Ti, 0. 002 7N, 0. 000 2B） with deformation extent 0 - 80% and strain rate 5 - 50 s^-1 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, and the fit precision is higher.
