摘要：
Pitting corrosion resistance of 2304 duplex stainless steel heat-affected zone with different cooling rates has been studied by potentiostatic critical pitting temperature (CPT) in 1.0 M NaCl. The results showed that, as cooling rate decreased from 100 to 10 degrees C/s in the temperature range of 1350-800 degrees C, the austenite fraction increased from 27.8% to 35.7%, and the CPT value increased from 14 to 19 degrees C. The morphologies after the CPT tests showed pitting occurred preferentially in the ferrite phase for all specimens. Moreover, relationship between pitting corrosion resistance and microstructure evolution was further discussed. (C) 2012 Elsevier Ltd. All rights reserved.
