keywords = {Degree of sensitization (DOS) assessment of particularly high alloy stainless steel is
still a scientific challenge. In this study; double loop electrochemical potentiodynamic
reactivation (DL-EPR) method in standard solution (0.5M H2SO4+0.1M KSCN; ASTM
G108-94 recommended for SS304 alloy) and a new proposed solution containing 1M
H2SO4+0.2M KSCN was used for measuring DOS of duplex stainless steel (DSS)
2205. The specimens were sensitized at 650ºC for 10; 60 and 300min. Although
DOS value at low sensitization time in standard solution was higher than proposed
solution (6% and 0.66% for 60min sensitized specimen in standard and new solution;
respectively); However; in standard solution; the trend of measured DOS by increase
in sensitization time was not acceptable; since 300 min sensitized specimen showed
lower DOS value (1%); while in new solution it reached to 5%. As a conclusion; the
new solution gives more reliable results and is proposed for measuring DOS of
DSS2205.},
