Abstract

Applications of the grain boundary etching method (GEM) were made to a low alloy CrMo steel, an austenitic Fe-40%Ni alloy and an Fe-3%Si alloy by using an etching solution which is valid for detecting P at grain boundaries of NiCr steels. The polarization characteristics in 0. 5 kmol/m**3 H//2SO//4 solution were also measured. It was concluded that any steels to which GEM is applicable should have surface stabilities similar to those of NiCr steel. The measurement of polarization curves helps assess GEM applicability to given steels.
