Influence of the carbon content and of a plastic deformation on the corrosion behaviour of cast carbon steels. Part 1:Microstructure and compression properties

Manale Belhabib, Patrice Berthod

Plastic deformation or hardening leads to disorder in the crystalline structures of metals and alloys, and this deterioration may decrease their corrosion resistance. This concerns notably iron-based alloys, steels or cast irons. In this work it is wished to study such possible effect on simple binary carbon steels for carbon ranging from 0 to 1.6 wt.%C, in the simplest conditions: elaboration by casting, hardening by compression and corrosion in sulphuric solution, before exploring later more complex steels and cast irons, other modes of deformation and other aqueous solutions. In this first part these are the obtained microstructures, the hardness and compression properties which will be presented. A second part will be devoted to the corrosion behaviour and the influence of hardening of these electrochemical properties.
