AbstractOptical and electron metaliographic, X-ray diffraction, and electron microbeam probe studies of the interdiffusion of Cb-1 Zr alloy with type 316 stainless steel are reported. Extruded Cb-1 Zr alloy-type 316 stainless steel diffusion couples were heat treated at temperatures of 732, 871, 982, and 1093°C for time periods of US, 400, 900, 1400 hr. In no case was appreciable diffusion observed in specimens heat treated at 732°C for time periods chosen. Diffusion zones based on the systems iron-columbium and columbium-nickel-iron were observed in varying degrees in all other specimens. An activation energy for the rate-control ling process in the growth of the diffusion layers is reported. The growth rates of the observed zones were found to be retarded when these data were compared with data reported by other investigators for the interdiffusion of unalloyed columbiiim-type 316 stainless steel diffusion couples. Postulations arc made to explain this retarded growth rate and also to explain the growth of a nickel enriched columbium-iron-nickel-chromium intermetallic zone adjacent to the columbium.

AbstractCorrosion behaviors of 316 stainless steel (316 ss) and Inconel 625 alloy in molten NaCl–KCl–ZnCl2 at 700°C and 900°C were investigated by immersion tests and electrochemical methods, including potentiodynamic polarization and electrochemical impedance spectroscopy. X-ray diffraction and scanning electron microscopy/energy dispersive spectroscopy were used to analyze the phases and microstructures of the corrosion products. Inconel 625 alloy and 316 ss exhibited high corrosion rates in molten chlorides, and the corrosion rates of these two alloys accelerated when the temperature increased from 700°C to 900°C. The results of the electrochemical tests showed that both alloys exhibited active corrosion in chloride molten salt, and the current density of 316 ss in chloride molten salt at 700°C was 2.756 mA/cm−2, which is about three times the value for Inconel 625 alloy; and the values of the charge transfer resistance (Rt) for Inconel 625 were larger than those for 316 ss. The corrosion of these two alloys is owing to the preferred oxidation of Cr in chloride molten salt, and the corrosion layer was mainly ZnCr2O4 which was loose and porous and showed poor adherence to metal.
