| 摘 要： | 用扫描电镜和电子探针研究了低碳锰钢中的周期性带状组织，结果表明，在全部研究用钢中，钢锭经热轧后均出现这种组织，其严重程度随钢的成分而异，并随坯带加工顺序而增加，带状组织与锰的显微偏析等因素有关，适当的调整碳锰以及形成模跨铁素体带的转变产物可降低带状组织的严重程度。

| Abstract: | Periodic banding phenomena in carbon manganese steels with three different composition levels of Mn and four different levels of carbon have been studied by SEM and microprobe analysis. The experimental results showed that: In all the alloys studied, banding formed after hot rolling of the ingot, but the severity of banding varied with composition; Formation of banding is related to microsegregation of manganese in the ingot and hot band; The severity of banding can be reduced by (a) properly adjusting carbon and manganese and (b) by the formation of transformed products breaking through the ferritic bands. |
