Abstract

The reheating of high aluminum content Transformation Induced Plasticity (TRIP) and Light Weight steels in a nitrogen-rich atmosphere has been shown to cause development of aluminum nitride precipitates in addition to an oxide scale. It is important to understand how these nitrides form and their consequences for the surface quality of galvanized products. This study looks at model Fe-Al (up to 8 wt.% Al) alloys and uses Confocal Laser Scanning Microscopy, XRD, SEM-EDS, and TEM to study the effect of various atmosphere compositions and heating rates on the growth and development of these precipitates in a subsurface oxygen-depleted region.
