摘要
本文研究了镍基变形高温合金Nimonic91中γ′相的长大及分布规律。在一定的时效时间内,γ′相的平均直径随时效时间的立方根增加而线性增加。然而,经长时间时效后,γ′的长大偏离这规律。
The γ' particle coarsening in the Nimonic 91 has been studied after heat-treatment at 2 different temperatures and for times up to 5832 hours. For moderate times in all cases the mean γ' dimension increased linearly with the cube root of time. However, at high values of time some deviations from this behaviour were observed.
