Abstract
In this paper, the limitations of conventional reagents for the metallographic preparation of nickel-based alloys and, in particular, of the IN-657 alloy, which is the object of this study, are revealed. A reproducible method has been developed for the metallographic preparation of IN-657, using electropolishing with diluted H2SO4 and high temperature controlled oxidation.
