Abstract
Turbine blades are subjected to creep deformation through their continuous centrifugal loading during operation. In addition to this, hot corrosion in gas turbines limits the durability of even the best blade materials at present available. In this article, an attempt has been made to evaluate the effect of hot corrosion due to sodium sulphate, sodium chloride and sodium metavanadate salt mixture on creep rupture of a cast nickel base turbine blade superalloy.
