Abstract

The microstructural and textural aspects of the substrates and the coatings on three industrially galvannealed interstitial free, interstitial free high strength and low carbon high strength quality grade steels have been carefully evaluated to determine their effects on the powdering resistance behavior of the coatings. A high amount of delta phase and a non-basal {01.3}‹uv.w› texture in the coating along with low Fe content have been found beneficial in this respect.
