Abstract
Changes in the microstructures of FeGe2-Ge, CoGe2-Ge, and NiGe-Ge allo ys after anodic etching at various potentials in 1 N H2SO4 are studied by means of scanning electron microscopy and microprobe analysis. It is shown that the Ge phase dissolves preferably whereas the MeGe phase is more stable. The anodic behavior of FeGe2-Ge and pure intermallide FeGe2 is studied. The intermetallic FeGe2 phase in alloy is more resi stant than the individual intermetallide FeG(2).
