Full TextAbstract
In this study effect of different ageing conditions on intergranular corrosion, pitting corrosion and relation between critical pitting temperature (CPT) and degree of sensitisation (DOS) was investigated by potentiostatic polarisation and double loop-EPR methods. The results showed by increasing sensitisation time, DOS increased and measured CPT value decreased. In addition the values of DOS and CPT of specimens aged at 650 C showed almost liner relation while this correlation was diminished for the specimens aged at 800 C. The results may be attributed to the further formation of precipitates on specimens aged at temperature of 800 C.
