Growth of Nanostructure on Cu_0.62Zn_0.38 after SMAT during Thermal Oxidation

Abstract:

Commercial Cu_0.62Zn_0.38foil was subjected to surface mechanical attrition treatment (SMAT) processing. The original and SMAT Cu_0.62Zn_0.38 foils are thermally oxidized at 500°C under N₂-5%O₂ gas environments, at a pressure of 1 atm for 3 hours. The oxidized specimens were characterized with a scanning electron microscope, an X-ray diffractometer. It is found that nanosheets are easily formed on the SMAT specimen surface. The favorable formation of nanosheets relates to twin–matrix lamellae structure.
