摘要

通过定量相分析研究了Nb-Ti微合金化超低碳烘烤硬化钢(%:0.002C、0.01～0.02Nb、0.01～0.02Ti、0.002 8～0.004 2N)的析出相

建立了试验钢固溶C含量的计算公式。结果表明

随固溶C含量计算值的增加

钢板的烘烤硬化性BH

值增大;随冷轧板退火温度(810～850℃)的增加

值增加;820℃退火时

640℃卷取的钢板BH

值高于710℃卷取的钢板BH2值。

Abstract

Precipitates in Nb-Ti microalloying ultra-low carbon bake hardening steel ( % : 0. 002C

0. 01 ~0. 02Nb

0. 01 ~0. 02Ti

0. 002 8 ~0.004 2N) have been studied and expressions for solution C content in test steel were established by quantitative phase analysis. Results showed that increasing calculated value of solution C content

the bake hardening BH

value increased； with increasing annealing temperature (810 ~ 850 °C ) of cold rolled plate

the BH

value increased ；and as annealed at 820 °C

the BH

value of plate coiled at 640 °C was higher than that coiled at 710 °C.
