Abstract
The 7000 series of aluminum alloys are primarily used in the aerospace industry as structural components and are strengthened
by age-hardening especially 7075-T6 aluminum alloy. This study aims to improve properties of 7075-T6 such as impact
toughness, thermal age hardening behavior and corrosion resistance in 3.5% NaCl solution by using quenching in 30%
polyethylene glycol and addition alloying elements, i.e. boron (B) to this alloy. Results showed that the addition 0.1% B to the
base alloy improves impact toughness by (30%) when quenching in water, and by (50 %) when quenching in 30%PAG
corresponding to the base alloy at aging temperature 150?C. Also results showed that the thermal age hardening behavior
improved when we add0.1% B (b alloy) by (18%) at aging temperature 150?C in comparison to the base alloy. An improvement
of corrosion resistance in 3.5% NaCl solution when adding 0.1%B (b alloy) by (234 %) at aging time 150?C in comparison to
the base alloy.
