The phase diagram of the - system is complicated, and eutectic hydrates such as - and -2 occur.

体系的相图是复杂的，产生象·和·2之类的低共熔水合物。

The results indicate that AZ91 alloy does not solidify following the phase diagram under the experimental conditions, but precipitate eutectic;

实验结果表明，在正常凝固条件下，AZ91合金并不按平衡相图凝固，而是有共晶相析出；
