提出了一种定量评定铁素体—珠光体带状程度的参数(带状密度),分析了取不同特定长度值时的带状密度与带状级别的关系,并比较了用两种评估法考察冷却速度对带状组织影响的结果。 A parameter (band density) for quantitatively evaluating the ferrite-pearlite banding degree was proposed. The relationship between band density and banding density was analyzed when taking different specific length values. The comparison between two methods The effect of cooling rate on the banded structure was examined.
