Abstract :
- Series xxx7 alloys are produced from
aluminum alloys by adding mainly zinc, Zn, magnesium,
Mg, copper, and Cu to aluminum. They have high
mechanical properties that distinguish them from other
aluminum alloys. In this research, the effect of adding
different percentages of nickel [1 0.5, 0.1,] %Wt., and
different heat treatments, namely the 6T artificial aging
treatment, and the reflux treatment, usually aging and
RRA, on the tensile properties, Vickers hardness, and
microstructure of aluminum alloy 7075 was studied.
Habit of aging. It has been shown that the reflux and
RRA treatment gives better results than the 6T artificial
aging treatment, and the adding of nickel in general has
led to a softer crystalline structure of the studied alloy
and higher values of Vickers hardness and tensile
properties of the alloy.
