Nevertheless, there is no consensus about the temperature to achieve the highest fragmentation of metastable phase. On the whole, the size and distribution of dispersoids are dependent on the fabricating method and complementary steps.

The samples wire cut from the profile. Then, "semi dispersion treatment" was done in a way, in that the samples which were quasi dissolved at 600°C for 8h followed by water quenching, and then semi aged at temperatures of 300, 400, and 500°C for 1 hour.
