Popis: | Microstructure evolution of alloy with composition Al – 3.4 Zn – 1.9 Mg (at. %) was tracked using high resolution imaging and electron diffraction during ageing at 120 °C after being initially natural aged for 4 days. Hydrogen was charged in microstructure by cutting samples in Electrical Discharge Machine immediately after being quenched from solid solution temperature. Transmission Electron Microscope observations revealed a higher presence of high aspect ratio GPII-zones in microstructure of hydrogen charged and aged samples. Correlation was made with previously reported hydrogen effect into vacancy formation. |
