主 题：2205/Q235B clad steel plate Pass reduction ratio δferrite Decarburization layer-Shear strength
摘 要：2205/Q235B clad steel plates were fabricated using a thermal *** metallographic microscope,scanning electron microscope,energy-dispersive spectrometer,shear test,electrochemical corrosion test and acid immersion test were used to study the influence of the pass reduction ratio on the microstructure and properties of 2205/Q235B clad steel *** results show that the clad steel plates had a good bonding surface when the pass reduction ratios were between 16.3%and 36.0%.There existed the mutual diffusion effect of elements near the bonding surface,which caused the long austenite strip on the side of 2205 stainless steel and the decarburization layer on the side of Q235B low-carbon *** transformation ofδferrite toγaustenite and the generation of the decarburization layer were promoted because of the lower pass reduction *** corrosio n resista nee of 2205 duplex-phases stainless steel worse ned by the decrease in 8 ferrite con *** increase in the decarburization layer thickness made the shear strength of the clad steel plates reduce from 453 to 390 *** potential of the decarburization layer was lower than that of 2205 stainless steel and Q235B low-carb on steel,which was easily corroded in the corrosive medium.
