The interpretation of austenitic stainless steel weld metal microstructure requires an understanding of the solidification and solid state transformation metallurgy of this class of alloys. The room temperature microstructures are complicated by the fact that ferrite is only stable at high temperatures. The alloy composition and weld cooling rates can influence both the form and amount of ferrite present in the room temperature microstructure. Optical microscopy can be a valuable tool in studying both weld metal solidification and transformation mechanisms and the related problem of solidification hot-cracking.
