Abstract
The microstructure of weld metal of duplex Fe-30Mn-9Al-0.4C alloy was investigated using optical metallography and transmission electron microscopy. It was found that DO 3 superlattices having an ordered FCC structure precipitated in the ferrite phase during autogenous gas tungsten arc welding. Two types of antiphase boundary were observed between precipitates in the Fe-Mn-Al weld metal.
