Dilatometric analysis of cementite dissolution in hypereutectoid steels containing Cr

Abstract

Cementite dissolution in hypereutectoid steels containing Cr is analyzed using dilatometry combined with consideration of the carbon content in the austenite. The results suggest that the austenite transformed from the mixture of ferrite and cementite has a carbon content that corresponds roughly to equilibrium with ferrite. The overall dissolution behavior of cementite is described well with the suggested analytical procedure. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
