ABSTRACT:
A method for revealing the microstructure of metal alloys which comprises the steps of polishing the sample, chemically etching the polished metal surface, thermally etching the chemically etched surface and quenching the thermally etched sample. This method allows observation of deformed and recrystallized grains on the same polished surface and provides the opportunity to correlate recrystallized grains to their nucleation sites.
