摘要
Geometrical Close Packed(GCP) phase in Fe-Cr-Ni alloy was quantitatively isolated and precisely determined when electrolyzed in 10%H_3PO_4 electrolyte at a low current density of5 mA/cm^2 and 22 ℃±1 ℃.The transpassive dissolution potential of the alloy matrix under above conditions is about 1 140 mV(SCE),at which GCP phase is in passive state and can be isolated from the alloy.
