The effect of equal channel angular pressing (ECAP) and further cold upsetting (CU)
process on the kinetics of precipitation during aging of solid solution treated 7050 Al alloy …

Abstract Al-Zn-Mg-Cu alloys with a low Zn/Mg ratio have attracted considerable attention in
recent years as a result of an attractive property portfolio based on their ability of age …

In this work, a new four-stage aging treatment by employing a natural aging prior to re-aging
is designed to promote GP zones formation and subsequent shear-able strengthening effect …

In this study, a novel strategy is proposed to address the challenge of balancing strength
and corrosion in deformed Al-Zn-Mg-Cu alloys. The alloy was strengthened by equal …

Abstract Al-Zn-Mg-Cu alloy profiles are widely used as aircraft components because of
lightweight and high strength. The section of thin-walled profile is easy to have unavoidable …

Lightweight of automobile has drawn increasing attention due to the demand for energy
saving and emission reduction. High strength aluminum alloy sheet shows great potential in …

The influence of minor Ag on the precipitation evolution of the Al-4.2 Zn-2.8 Mg-1.0 Cu
(wt.%) alloy from early stages to over-aged stages at 150° C was investigated. Surprisingly …

Microstructure, mechanical properties and wear behavior of severely deformed Al-7075
alloy by equal channel angular pressing (ECAP) were studied. Microhardness, tensile and …

Equal channel angular pressing (ECAP) of AA7075 alloy, at room temperature, with six
