Abstract

The present paper highlights the effect of Na2so4 and NaCI salt mixture on creep rupture properties of Nimonic-263 alloy at 800 and 850 degrees C. Results revealed that for short duration tests, the rupture life is not much affected by the corrosive action of the salt mixture at both the temperatures. Whereas for long term creep tests, salt mixture affects the creep rupture properties of the material catastrophically. Minimum creep rate increases marginally for salt deposited sample compared to the bare alloy. Fractographic features of the ruptured salt deposited and bare samples have been discussed.
