TL;DR: In this article, the influence of heat treatment on strength, exfoliation corrosion and electrochemical behavior of 7085 aluminum alloy has been investigated by tensile testing and EIS combined with transmission electron microscope (TEM).

TL;DR: In this article, the effect of repetitious-retrogression and reaging (repetitious-RRA) treatment on the strength and SCC resistance of Al-Zn-Mg-Cu alloy was investigated by the slow strain rate technique (SSRT) and electrical conductivity test, using TEM, EDS and SEM.

TL;DR: In this article, a series of compression testing over a temperature range from 300°C to 450°C with strain rate from 0.0001−s −1 to 1 s −1.

TL;DR: In this article, the influence of heat treatment on stress corrosion cracking resistance of a low-Cu containing Al-Zn-Mg-Cu aluminum alloy was investigated, and the results showed that the stress corrosion crack resistance was significantly improved by step-quench and aging heat treatment whereas retrogression and re-aging heat treatment and two-stage over aging heating treatment could hardly enhance the cracking resistance compared with peak aging.

TL;DR: In this article, the influence of quenching rate on microstructure and stress corrosion cracking (SCC) of 7085 aluminum alloy was investigated by tensile test, slow strain rate test (SSRT), combined with scanning electron microscopy (SEM) and electrochemical test.
