Abstract
The purpose of this study is to identify the crystal structure of metastable phase in Ag
added Al-Mg-Si alloy to compare the formation of β’-phases in Al-Mg-Si alloys without Ag, using
images of high resolution transmission electron microscope (HRTEM), selected area electron
diffraction (SAED) patterns and an energy dispersive X-ray spectroscopy (EDS). The result of
SAED patterns and HRTEM images have been simulated and compared with images then SAED
patterns obtained from actual precipitates. SAED patterns and HRTEM images obtained from
metastable phase in the Ag added Al-Mg-Si alloy showed similar to those of β’-phase in Al-Mg-Si
alloy without Ag and the lattice spacings changed because of the effect of Ag.
