Abstract

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.
