Influence of heat treatment and chemical composition on the magnetic properties of ferromagnetic steels

Abstract

An investigation into the effects of carbon content and heat treatment on the magnetic properties of steels has been carried out. This is a precursor to more extensive work on the influence of microstructure on the magnetic properties of Fe-C alloys. It has been found that for similar heat treatments the coercivity and remanent magnetisation increase with carbon content. Different heat treatments of the same specimen also affect the magnetic properties.
