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。

Abstract

Hot compressive test of Φ8 mm X 12 mm cylinder test specimen of ultra-low carbon steel M21 ( % : 0. 003C

0. 045Al

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.
