摘要

The effect of copper on precipitation sequence of Al-Mg-SI alloys has been studied and discussed by many researchers. However, there is no suitable explanation yet. We are studying precipitation sequence of Al-Mg-Si alloys by using high-resolution transmission electron microscopic (HRTEM) technique. Several metastable phases and their crystal structures as well as the lattice parameter have been determined by our previous research. We have found the segregation of copper happening at the interface between the Q'-phase in the Al-Mg-Si-Cu alloy by energy-filtering TEM (EFTEM). Also, strange shape precipitate was found at that time and we have reported about it at the 8th ICAA [1]. In this work, we observed the precipitate, which has the elongated shape in the sample annealed at the early stage during aging and discussions about its crystal lattice and the differences between this precipitate and the normal ones in this alloy, for example, Q'-,b"-,b'- phases were presented.
