Corrosion behavior of AA2037 T8 Al alloy in a 1 M NaOH aqueous solution was investigated using slow positron beam, together with microscopy techniques and electrochemical tests. The alloy was homogenized at 510 °C for 2 h and 30 s, respectively, before final peak aging, so that one Sample A had more dispersoids than Sample B after homogenization. It was found that S parameter of the Doppler-broadened...
Hydrogen‐ and corrosion‐induced microstructure and defects of ZnO single crystal under acidic conditions have been studied by using slow positron beam spectroscopy and microscopy techniques. Slow positron beam measurements revealed that a near‐surface damaged region with a high concentration of defects was formed after hydrogen charging, but not after corrosion. The formation of hexagonal pyramids...
