1Uniform corrosion behavior of FeCrAl alloys in borated and lithiated high temperature water显示文摘The uniform corrosion behavior of model FeCrAl alloys as well as commercial Zircaloy-4 as reference material were investigated in 360℃borated and lithiated water.The results reveal that FeCrAl alloys exhibited better corrosion resistance than Zircaloy-4.It is found that the oxide films formed on the FeCrAl alloys are composed of outer Fe_(3)O_(4)layer,inner layer consisting of compact spinel layer and porous spinel layer,and transition layer containing Al-Cr-rich oxides and matrix enriched with Fe°.The spinel oxides in the inner layer are FeFe_(2-x-y-z)Cr_(x)Al_(y)MozO_(4).The corrosion mechanism of FeCrAl alloys in high temperature water is discussed.Fangqiang Ning Xiang Wang Ying Yang Jibo Tan Ziyu Zhang Dan Jia Xinqiang Wu En-Hou Han 2021Journal of Materials Science & Technology2021,,11:6
2Effects of thiosulfate and dissolved oxygen on crevice corrosion of Alloy 690 in high-temperature chloride solution显示文摘The crevice corrosion behavior of Alloy 690 was investigated in high-temperature chloride solution containing different concentrations of thiosulfate(S_(2)O_(3)^(2-)) and dissolved oxygen(DO). The S2O32- inhibited corrosion of Alloy 690 through consuming oxygen in aerated chloride solution. In deaerated chloride solution,the S_(2)O_(3)^(2-) was reduced to S° and S^(2-) and subsequently incorporated into the oxide films, which promoted the pitting corrosion at locations of both TiN inclusions and matrix inside the crevice during the crevice corrosion as well as influenced the composition and thickness of the oxide films. The effect mechanisms of S_(2)O_(3)^(2-) and DO on crevice corrosion in high-temperature chloride solution are discussed.Fangqiang Ning Jibo Tan Ziyu Zhang Xinqiang Wu Xiang Wang En-Hou Han Wei ke 2021Journal of Materials Science & Technology2021,,7:2
3Role of welding residual strain and ductility dip cracking on corrosion fatigue behavior of Alloy 52/52M dissimilar metal weld in borated and lithiated high-temperature water显示文摘Corrosion fatigue behavior of Alloy 52/52 M dissimilar metal weld(DMW)was investigated in borated and lithiated high-temperature water.The fatigue life of Alloy 52/52 M DMW in high-temperature water decreased in comparison with that in air.The fatigue cracks initiated at Alloy 52 M butt weld or at the interface of Alloy 52 buttering and Alloy 52 M butt weld.The welding residual strain and ductility dip cracking in Alloy 52 M butt weld promoted the initiation and propagation of fatigue cracks.The environmentally assisted fatigue damage in high-temperature water is discussed by taking account of microstructure defects.Jun Gao Jibo Tan Ming Jiao Xinqiang Wu Lichen Tang Yifeng Huang 2020Journal of Materials Science & Technology2020,42,7:1
4Effects of 405 stainless steel on crevice corrosion behavior of Alloy 690 in high-temperature pure water显示文摘Effects of 405 stainless steel(405 SS) on crevice corrosion behavior of Alloy 690 in high-temperature pure water were investigated.Results revealed that the corrosion rate of Alloy 690 was low within the crevice.It was likely attributed to the fact that a Cr-rich inner oxide film and a Ni-rich layer beneath this oxide film formed upon Alloy 690,inhibiting the diffu sion of oxygen towards the oxide/matrix interface.Moreover,the Fe2+ions dissolved from 405 SS consumed most of oxygen,leading to less oxygen participating in the oxidation of Alloy 690.In addition,it was found that Fe concentration continuously decreased from the surface of the inner oxide film to the oxide/matrix interface of Alloy 690 within the crevice,which was probably due to the diffusion of Fe2+ions dissolved from 405 SS into the inner oxide film.Fangqiang Ning Jibo Tan Xinqiang Wu 2020Journal of Materials Science & Technology2020,47,12:1
