Abstract

The purpose of this study is identity the crystal structure of metastable phase in Ag added Al-Mg-Si alloy by comparing that of the β'-phases in Al-Mg-Si alloy without Ag, using images of high resolution TEM (HRTEM), selected area electron diffraction (SAED) patterns and energy dispersive X-ray spectroscopic (EDS) analysis. The result of SAED patterns and HRTEM images has been simulated and compared with actual images and SAED patterns obtained from actual precipitates. SAED patterns and HRTEM images obtained for the 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 had different spacings of crystal lattice because of the effect of Ag. The quaternary Al-Mg-Si-Ag intermetallic compound has been also confirmed in the Ag-addition alloy.
