Investigation of Alloy‐Dependent Occurrence of Ferromagnetism in Carbon‐Expanded Austenitic Steel after Low‐Temperature Surface Hardening

Abstract

Formed magnetic domains in carbon expanded austenite are subject to grain orientation dependence. A labyrinthine domain structure could be detected mainly in the <001> orientation (a). Visualization of the magnetic domain structure could be achieved in similar quality using Ferrofluid (b) MFM (c).
