Aiming at traditional peak aging of 7A04 Aluminum Alloy with high strength but low corrosion resistance, innovative gradually cooling three-step aging heat treatment process were designed, conventional mechanical properties and corrosion resistance of 7A04 aluminum after three kinds of aging treatments was studied through microstructure. The results show that compared with the traditional peak aging process, two gradually cooling three-step aging process is to improve materials tensile strength, plastic and impact toughness in different degrees. Meanwhile corrosion resistance of materials has improved significantly. And extension of low temperature aging time is conducive to the further improvement of strength.

Mechanical Properties And Corrosion

In this paper, the samples were heat treated by two-stage artificial aging to investigate the effect on the mechanical properties of the 7150-T77 aluminum alloy, and finally subjected eventually to the ESCO corrosion test according to ASTM G34-01 standard. The results have shown that the mechanical properties and corrosion resistance induced by cracking at alloy 7150 can be improved by two-stage customized heat treatment for a specific application in the aeronautical industry.
