【Abstract】 The homogenizing annealing experiment with different processes was carried out on the newly developed as-cast samples of highly-alloyed Al-9. 0 Zn-2. 06 Mg-2. 12 Cu-0. 13 Zr aluminum alloy. The suitable homogenizing annealing mechanism was determined after DSC curve analysis and structure observation. The results show that the two-stage homogenizing annealing mechanism is suitable for the experimental alloy,which is 430℃ 12 h + 470℃ 60 h.更多还原
