Abstract

Influence of the Si content in steels on their mechanical and chemical behaviors. Part 1: Properties in compression, hardness and high temperature oxidation

Author(s): Elodie Conrath, Patrice Berthod, Lionel Aranda

Most of steel products are available as sheets, therefore shaped by cold- or hot-rolling. Such processes induce plastic deformation. On the one hand this ismore or less difficult to achieve, this depending on the microstructure or simply on the chemical composition of the steel, notably concerning the more common elements present in steels: carbon and silicon. On the other hand the same elements also act on the behaviour of the hardened steels in high temperature oxidation in the case of hot working, and on room temperature corrosion in aqueousmilieu in both families of fabrication routes. In this work the effects of the silicon contained in a simple ternary steel on its formability and on its high temperature and room temperature chemical properties will be characterized. In this first part, four ternary steels with different silicon contents (0.1 to 0.25w%) were elaborated by foundry, plastically deformed in compression, then subjected to high temperature oxidation as this can be encountered on the steel sheet surface during the last cooling fabrication stage.
