Texture, Microstructure and Properties of Coatings on a few Industrially Produced Galvanized and Galvannealed Interstitial Free Steels

Abstract

The substrate steel texture appears to control the texture of galvanized and galvannealed coatings on interstitial free steels. Again, the powdering resistance of coatings depends on the type of textures produced in them. An attempt has been made to correlate the textures of the substrate and the coating with the forming behavior of the latter. In the galvannealing operation, using lower galvan-nealing power (lower strip temperature) improves the coating formability. The formation of an almost continuous {01.3}< uv.w > fiber and lower amount of iron present in the coating layer could be the possible reasons for this behavior.
