| description | This work has objective to correlate the intergranular corrosion susceptibility test named EPR-DL (Electrochemical
Potentiokinetic Reactivation of Double Loop) with the sigma phase formation and other phases. It has been used samples
from a UNS S32760 steel pipe for conducting various aging heat treatments. Held isothermal heat treatment at 850°C
for 1 min, 10 min, 30 min, 1 h, 1h30min and 10 h. Each heat treated sample and as received were tested using the
electrochemical polarization reactivation of double loop technique (EPR-DL). It was possible the detection of deleterious
phases with DL-EPR portable cell. The EPR-DL test of some samples showed a second peak of reactivation in which the
results showed that this peak might be associated with ferrite or be related to the presence of chi phase |
