摘要

研究了CSP工艺生产的0.04%C低碳钢DC03 2.9 mm热轧基板、0.9 mm的冷轧板和退火平整板的组织与织构。结果表明

热轧基板组织为铁素体+少量沿晶界分布的珠光体

铁素体基体中有少量40～100 nm MnS粒子

没有观察到AlN;冷轧板组织为含大量位错的带状铁索体-珠光体

{111}织构的择优取向较明显;退火平整板组织为铁素体和游离渗碳体

并观察到10～30 nm的析出相

{111}织构轴密度达5.15

{100}轴密度减为0.61。

Abstract

The structure and texture of 2.9 mm hot-rolled plate

0.9 mm cold-rolled sheet and annealed temper-rolled sheet of 0.04C low carbon steel DC03 produced by CSP process have been studied. Results showed that the structure of hot-rolled base plate was ferite matrix + a small amount of pearlite dispersed along grain-boundary

there was a little 40~ 100 nm MnS particles in ferrite matrix

and the AlN wasn't observed; the stricture of cold-rolled sheet was banded ferrite-pearlite containing a large amount of dislocation

and the {111} texture orientation was obvious in cold-rolled sheet; and the annealed temper-rolled sheet structure was ferrite and free carbide with a few of 10～30 nm precipitates

and the density of {111} was upto5.15 while the density of{100!decreased to 0.61.
