选择锂(Li)作为合金元素是由于Zn+β-LiZn₄共晶组织，在Zn-Li二元相图(图1(a))中得到验证，在Zn-0.4Li和Zn-0.7Li (wt%)合金中得到验证。β-LiZn₄ 为密排六方结构(HCP)，晶格参数a = 0.278 nm, c =

0.439 nm，如图1(b)所示。

Lithium (Li) is selected as an alloying element because of the possible hardening ability of the Zn+β-LiZn₄ eutectic structure, as shown in the Zn-Li binary phase

diagram (Fig. 1(a)), which has been verified in Zn-0.4Li and Zn-0.7Li (wt%)

alloy.β-LiZn₄ has a close-packed hexagonal structure (HCP) with the lattice

parameters of a = 0.278 nm and c = 0.439 nm, as illustrated in Fig. 1(b).
