Improved bake-hardening response of Al-Zn-Mg-Cu alloy through pre-aging treatment
TL;DR: In this article, the effect of pre-aging treatment on the bake-hardening response of an Al-Zn-Mg-Cu alloy was investigated, and it was determined that preaging immediately after quenching is an effective method to form stabilized Guinier-Preston zones, which can act as precursors to form the metastable η′ phase, and then improve the bake hardening response.

Microalloying of Sc, Ni, and Ce in an advanced Al-Zn-Mg-Cu alloy
TL;DR: Using transmission electron microscopy (TEM), scanning electron microscope (SEM), X-ray diffraction (XRD), and optical microscopy, the effects of microalloying elements of Sc, Ni, and Ce on the microstructure of a new super-high-strength ingot metallurgy (IM)/Al-Zn-Mg-Cu alloy (C912) have been correlated with mechanical properties and stress corrosion cracking (SCC) behavior as mentioned in this paper.

The nucleation of precipitates: The system Al-Zn-Mg
TL;DR: In this article, a semiquantitative theory has been developed for the formation of precipitate free zones at grain boundaries and the results have been used to develop a model of nucleation by vacancy/solute atom clusters.
