The results show that the corrosion rate of the aged alloy increases with aging time until1 193 h and thenceforwards decreases again. The T4 alloy shows the lowest corrosion rate, and the F alloy exhibits the highest corrosion rate.

结果表明，时效时间为193小时之前，合金的腐蚀速率随时效时间增加而增加，之后有所降低；T4态合金的耐蚀性最好，F态最差。

However, the technical practice of the alloy obviously appeared unsatisfication in hot working: The hot working temperature range is narrow and the fissures can be easily generated, The cracks were resulted from unappropriate operation.

但是该合金的工艺实践证明其热加工并不令人满意，热加工温度范围窄、且易产生发纹，控制不当，更易引起加工开裂，故热加工难度大，并严重影响合金质量和材料的成品率。
