چکیده
The influence of high energy-ball milling (HEBM) on corrosion and hardness age hardening aluminum alloys was investigated. Nanocrystalline (AA2024, AA6061 AA7075) were produced by HEBM pre-alloyed powder subsequent cold compaction under uniaxial pressure 3 GPa. Cyclic potentiodynamic polarization immersion tests conducted in 0.6 M NaCl solution which revealed significantly increased pitting protection potentials the compared to wrought same composition. X-ray diffraction analysis transmission electron microscopy indicated grain refinement below 100 nm ball milled major strengthening mechanism alloys. superior resistance attributed nanocrystalline structure, extended solid solubility homogenous microstructure- free from coarse intermetallic phases.
