通过透射电镜观察，在时效的Al-1.0质量% Mg2Si-0.5质量% Ag合金中发现了新的第四系晶界相。该析出物为Al-Mg-Si-Ag四元相，具有六方晶系，晶格参数大于Al-Mg-Si-Cu合金中的Q′相。
A new quaternary grain boundary precipitate has been discovered in aged Al–1.0 mass% Mg2Si–0.5 mass% Ag alloy by transmission electron microscopy. This precipitate is a quaternary Al–Mg–Si–Ag phase with a hexagonal crystal system and a lattice parameter larger than that for the Q′-phase in Al–Mg–Si–Cu alloy.
