研究了合金在不同处理制度下组织状态及γ＇相析出初期的长大规律．结果表明，析出初期与（ｔ１／２）成线性关系，合金ｋγ＇相的长大速度为２．８２×１０９×ｅｘｐ（－２０．３×１０３／Ｔ），合金中Ａｌ、Ｔｉ的平均扩散激活能为３４７ｋＪ／ｍｏｌ．
The growth of the alloy under different treatment regimes and the initial growth of γ ’phase were studied. The results show that the growth rate of the alloy kγ ’phase is 2.82 × 109 × exp (-20.3 × 103 / T), the average diffusion of Al and Ti in the alloy is linear with the initial value of (t1 / 2) The activation energy is 347 kJ / mol.
