Deformation Behavior during Solidification of Steels

Abstract

A high temperature tensile test of high carbon steels was executed in the temperature range of the mushy zone. Results were interpreted from the viewpoint of solidification progress which was estimated by numerical simulation of microsegregation. The minimum temperature among those at which ductility is zero corresponded to a solid fraction around 1 for high purity samples; this is because the brittleness in this temperature range is caused by the remaining liquid. Low purity samples exhibited a different ductility.
