HREM study and structure modeling of the η′ phase, the hardening precipitates in commercial Al-Zn-Mg alloys
(1999) In Acta Materialia 47(9). p.2651-2659- Abstract
- The structure of the η′ phase, one of the most important age-hardening precipitates in commercial Al-Zn-Mg alloys, has been studied at the atomic level by means of high-resolution electron microscopy (HREM). A structural model of the η′ phase has been constructed on the basis of the structural characteristics in the observed images and the structure of the η-MgZn2 phase. Image simulation of this model shows a good agreement between calculated and experimental images. Comparison of this model with the early existing model on the basis of the X-ray diffraction is also given.
