Passivation layers on U-AHSS and HSS

Key Information

U-AHSS and HSS have high deformation stresses during hot rolling. A simple route to avoid excessive stresses is the increase in temperature. Consequently, new studies are necessary to find possible passivation layers that will reduce excessive oxidation during steel processing (hot rolling).

The aim of this project is to build oxide maps for the phase composition of scales thermally grown on steels containing possible passivation layers of Cr, Si or Al.

Often it is not possible to obtain full protection against oxidation without altering mechanical properties. Therefore, the main objective is the reduction in oxidation even in a moderated manner without altering substantially mechanical properties. This will allow higher strip temperatures which in turn will reduce deformation stresses.

The project will involve thermodynamic studies, preparation of new alloys, thermogravimetric analysis and mechanical testing. Additional experiments will be carried out to determine the effect of cooling on steel microstructure and mechanical properties.

Project Aims

1.       Build oxide maps for the phase composition of scales thermally grown on steels containing possible passivation layers of Cr, Si or Al.

2.       Reduction in oxidation rates of U-AHSS and HSS

3.       In general, new oxidation resistant alloys that have similar mechanical properties to U-AHSS and HSS
