研究了不同 Cd 量对 ZLCu5MnA 合金显微组织和微区分布的影响。结果表明:镉的含量在0.3%以下时

在合金中呈均匀分布

在175℃时效时

析出的θ″与θ′相细小而均匀;当镉的含量大于0.3%以后

开始富积

含量越高

富集程度越大

时效时

θ″与θ′相的尺寸和间距增大

数目减少。

The influence of Cd content in Al-Cu cast alloy on its microstructure and distribution has been studied.The results show that

if Cd is less than 0.3%

it will be distributed well

θ″and θ′phas- es will be fine and uniform when the alloy is aged at 175 C

if not

it will be concentrated with its con- tent raised

θ″ and θ′phases will be increased in size and interval at the same ageing temperature

but decreased in quantity.
