The impact of the grain orientation of the base alloy on the orientation relations of the corrosion productsis presented. After 2 min–5 min exposure the formation of a multi-layered corrosion zone was discovered. Aclear orientation relationship between ferrite and the (Fe,Cr)3O4 spinel could be demonstrated. The obtainedresults show the importance of the grain orientation on oxidation resistance.

T1 - Spot welding and weldbonding of high strength steels for lightweight auto body manufacturing N2 - The resistance spot welding procedure is one of the most important joining technique in lightweight car body shell mass production. Especially for newly developed ultra high strength steels (UHSS) and advanced high strength steels (AHSS), this joining technique has more advantages than other thermal and mechanical joining procedures for thin Steel sheets. Additionally, the technique of adhesive bonding and its combination with the technique of resistance spot welding called weldbonding becomes more and more important. The weldbonding affords many advantages, e.g. improved crash performance, fatigue behaviour and corrosion resistance. The main target of the contribution is to show the influence of different joined ultra and advanced high strength steels on the process reliability for both the resistance spot welding process and the weldbonding process. In this connection the influence of surface conditions of the steel sheets, the applied adhesive and the choice of the welding parameters on the process reliability will be studied. The results for the weldbonding procedure are based on different adhesives. Based on the representation of welding current ranges by weldability lobes, Statements concerning the weldbonding process reliability for some special AHSS and UHSS will be given. The mechanical behaviour of spot welded and weldbonded joints for different AHSS and UHSS will be studied.
