Abstract

The β€œElectrochemical Potentiokinetic Reactivation” method has been employed to quantify the degree of intergranular corrosion of Alloy 800, with different Ti + Al content, aged in the range 500–650Β°C for times up to 5000 hours. The results were compared with the classical Rollason's curves obtained by means of the Strauss' test and a satisfactory agreement was found.

An explanation of the slight differences between both methods has been proposed on the basis of the passivity film morphology.
