Article Preview

The number and size of the precipitation of spherical Al3Zr particles, in aluminium alloy containing trace of Zr which subjected to different heat treatments, have been investigated by transmission electron microscopy. The results show that, the number of spherical Al3Zr particles is determined by the pretreatment, and that the size is determined by the homogenization. The number of spherical Al3Zr particles increases with prolonging the time of pretreatment between 0h to 48h and rising the temperature of pretreatment between 200°C to 400°C, and the size of spherical Al3Zr particles turn out to be the same. The size of spherical Al3Zr particles increases with prolonging the time of homogenization between 0h to 48h and rising the temperature of homogenization between 470°C to 500°C.
