摘要：

The microstructures of CuZnAlMnNi alloy after ion-polishing and subsequent exposure for 60 days in the ambient atmosphere were examined by transmission electron microscopy (TEM). It was found that a large number of fine oxide grains, with various sizes, appear homogeneously on the surface of the alloy after being held in atmosphere. The oxides form along the planes of stacking fault, at the plate boundaries or around the dislocations, resulting in the decrease of the stacking faults in the original quenched martensite plates, and even the complete disappearance in local zones.
