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 DO₃ 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.

Fe-30Mn-9Al-0.4C焊缝金属DO3组织的TEM研究

采用光学金相和透射电镜研究了Fe-30Mn-9Al-0.4C双相合金焊缝金属的显微组织。结果表明，自焊过程中在铁素体相中析出了具有有序FCC结构的DO3超晶格。在Fe-Mn-Al焊缝金属的析出相之间观察到两种类型的反相边界。
