7xxx aluminum alloys; strengthening mechanisms and heat treatment: a review
TL;DR: In this article, the authors gave the report of reviewing task of the previous researches done on the strengthening mechanisms and heat treatment of xxx aluminum alloys, the overall conclusion is that the most powerful and so the most common strengthening mechanism in xxx alloys is the precipitation hardening T heat treatment On the other hand stress corrosion is a problem in T treated xxxx alloys to address which researchers have turned to special heat treatment called RRA retrogression nbsp and nbsp re aging nbsp which nbsp picks nbsp strength nbsp from nbsp TNbsp and

Microstructure and Tensile Properties of ECAPed Mg-9Al-1Si-1SiC Composites: The Influence of Initial Microstructures.
TL;DR: The ECAPed composite with homogenization treatment (HT) exhibited finer grain size, higher fraction of dynamically recrystallized (DRXed) grains, weaker texture intensity, as well as the presence of dynamic precipitated Mg17Al12 phase compared to that without HT.

X-ray line broadening from filed aluminium and wolfram
G.K Williamson,W.H Hall +1 more
TL;DR: In this paper, the authors used a Geiger counter spectrometer to measure the changes in intensity distribution in the spectra of cold worked aluminium and wolfram and found that the line breadths may be attributed to simultaneous small particle size and strain broadening, the latter predominating at the higher Bragg angles.
