The Q’phase in an Al-1.0 mass pct Mg2Si-0.5 mass pct Cu alloy at a peak-aged condition of 523 K was observed by a high-resolution transmission electron microscope (HRTEM), in order to identify its structure and chemical composition, and was compared with the type-C precipitate in an Al-1.0 mass pct Mg2Si-0.4 mass pct Si alloy (the excess-Si alloy). The Q'phase has similar features to the type-C precipitate, according to results of electron diffraction patterns and images taken by the HRTEM, that is, they have similar hexagonal crystal lattices (a 5 1.04 nm and c 5 0.405 nm) to each other. The type-C precipitate in the excess-Si alloy was the ternary Al-Mg-Si phase, and the Q' phase was the quaternary Al-Mg-Si-Cu phase in the Al-Mg-Si-Cu alloy, as determined by energydispersive X-ray spectroscopic (EDS) analysis. 6061 is mentioned once.

M. Barabash; O. V. Sulgenko; T. N. Legkaya Sections of the phase diagram Al-Mg-Si with up to 35 at.% magnesium and 35 at.% silicon are constructed. The thermodynamic calculation and experimental analysis have shown that the conode of three-phase eutectic equilibrium L ? a-Al+Mg2Si, corresponding to the maximum temperature of eutectic transformation, does not coincide with the stoichiometric cross section between Al and Mg2Si in the Al-Mg-Si ternary system, but rather occurs toward the magnesium-rich side of the ternary diagram. A polythermal cross section, corresponding to this conode, has been constructed. Concentration-temperature parameters of the univariant eutectic transformation L ? a-Al+Mg2Si, as well as the boundaries of the domain of existence of alloys crystallizing with the formation of only two phases, namely, a-Al and Mg2Si, were determined. Modeling of phase equilibria involving solid and liquid phases in the ternary system Al-Mg-Si was carried out. The topology of the phase diagram is stable against a wide range variation of the adjustable parameters; the inherent form of the diagram seems well established. The reasons for this are discussed. no 6061 matches. Tue, 03 Dec 2013 00:00:00 GMT https://hdl.handle.net/11115/206 2013-12-03T00:00:00Z
