The effect of transition element on grain refinement of 7475 aluminum alloy sheet produced by warm rolling was investigated. The alloy which contains zirconium instead of chromium showed ultra fine structure with stable subgrain structure after warm rolling at 350°C, followed by solution heat treatment at 480°C. The average size of subgrains was about 2 μm in diameter. Furthermore, it became clear that zirconium in solution has the effect of stabilizing subgrains. That is, fine Al3Zr compounds precipitate during warm rolling, inhibit recrystallization and stabilize subgrains. While, in the case of the 7475 alloy with only chromium, recrystallization occurs during warm rolling, because chromium-bearing compounds precipitate in relatively large size and they have less effect of inhibiting recrystallization. Moreover, the alloy containing both chromium and zirconium showed a duplex structure with recrystallized grains and subgrains.
