Abstract Variable microstructures of 1Cr19Ni23N electrode de
posited metal were observed by scanning electron microscope and transmission ele
ctron microscope.The effect of RE on intergranular corrosion resistance of auste
nite deposited metal is discussed.The results showed that RE modified the micros
tructure of deposited metal,and it has strong effect on the quantity,morphology
and distribution of carbides.Intergranular corrosion resistance was increased o
wing to the lessening of carbide particles formed at austenite grain boundaries
and morphology changing from reticular to granular.
