Analysis of the carbon distribution in a dual phase steel by EBSD and APT — •Lars Schemmann and Stefan Zaefferer — Max-Planck-Institut für Eisenforschung GmbH

Dual phase steels have been invented in the late seventies and early eighties. They combine good mechanical properties, such as a high strength and good formability. Even though they are produced at present time routinely by all big steel companies, some fundamental properties are not perfectly understood. This study focuses on the distribution of carbon in the steel, whereby the gradients at the ferrite martensite border are of special interest. On a microscopic level a combination of EBSD and EDX is used to identify areas of interest. These areas are subsequently analyzed using atomic resolution APT.
