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.
