查询词典 cast

The results obtained by XRD show that the as-cast and quenched alloys have a multiphase structure, including theNi3 phase, LaNi5 phase and LaNi2 phase. The substitution of Al for Ni increases the amount of LaNi2 phase in the as-cast alloys, but it has an inappreciable influence on the abundance of the LaNi2 phase in the as-quenched alloy.

X射线衍射分析结果表明：铸态及快淬态合金具有多相结构，包括Ni3相、 LaNi5相和一定量的LaNi2相； Al替代使铸态合金中LaNi2相的量显著增加，但对快淬态合金中LaNi2相的相丰度影响不显著。
