Abstract Al-Zn-Mg-Cu alloys (7xxx series Al alloys) are extensively used for their superior
mechanical and corrosion performance. These properties are microstructure-sensitive and …

Both preliminary heat treatment and final heat treatment play an irreplaceable role in the
production of aluminum alloy products. The homogenization degree of compositions, the …

The mechanical properties, corrosion behavior, and microstructures of Al-Zn-Mg-Cu alloy
during non-isothermal ageing (NIA) process were investigated. The results suggest that …

In ultra-high strength Al-Zn-Mg-Cu alloys, traditional heat treatments such as peak aging,
two-stage aging and retrogression and re-aging cannot perfectly balance the relationship …

The formation of unusual secondary precipitation zones (SPZ) within the primary
precipitation free zones (PFZ) effectively reduces the PFZ width, associated with finer grain …

A variable-rate non-isothermal aging (NIA) process that has two-stage heating and cooling
procedures was proposed for a ternary Al-Zn-Mg aluminum alloy aiming to obtain the …

In this work, the effect of non-isothermal aging treatment with the heating rate of 20, 40 and
60° C/h on the precipitation behavior and mechanical properties of the Al-Cu-Mg-Ag alloy …

The effects of increasing levels of pre-deformation on the mechanical properties and
microstructure evolution (dominantly T 1 phase) of an extensively used aerospace Al-Cu-Li …

The desirable properties and homogeneity of Al-Zn-Mg-Cu alloy thick plate are urgent to
acquire in the industrial field. An efficient method for determining the optimal non-isothermal …

Abstract The 7N01-T5 alloy (AT5) and 7N01-T4 alloy (AT4) were butt welded by metal inert
gas (MIG) welding with ER5356 filler wire, and the mechanical properties and corrosion …
