中文摘要

准晶相（I相）具有硬度高且与镁基体界面能低的优点，是一种理想的增强相。在Mg–Zn–Nd体系中，通过常规铸造方法即可制备出球状准晶相，其弥散分布的方式有利于提高镁合金的力学性能。但是，关于Mg–Zn–Nd体系准晶相的稳定性、晶体结构、形成条件和转变路径尚不明确，限制了准晶增强镁合金的设计与应用。本文采用高角度环形暗场扫描透射电子显微镜研究了Mg₄₀Zn₅₅Nd₅准晶的晶体结构，通过差示扫描量热法和退火实验研究了Mg–Zn–Nd体系准晶相的稳定存在的条件和转变过程。结果表明，铸态合金中的准晶呈云朵状，具有5次、4次、3次和2次对称轴，Nd原子沿5次轴形成边长为0.3 nm和0.8 nm的五边形，沿其它轴呈直线排列。Mg或Zn原子沿3次轴和2次轴形成边长为0.3 nm的六边形。Mg–Zn–Nd体系中的准晶是一种亚稳相，当温度高于300°C时，Mg₄₀Zn₅₅Nd₅准晶分解为稳定的三元相Mg₃₅Zn₆₀Nd₅、二元相MgZn和α-Mg。

Icosahedral quasicrystal structure of the Mg₄₀Zn₅₅Nd₅phase and its thermodynamic stability

Abstract

Abstract

The quasicrystal phase is beneficial to increasing the strength of magnesium alloys. However, its complicated structure and unclear phase relations impede the design of alloys with good mechanical properties. In this paper, the Mg₄₀Zn₅₅Nd₅ icosahedral quasicrystal (I-phase) structure is discovered in an as-cast Mg–58Zn–4Nd alloy by atomic resolution high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). A cloud-like morphology is observed with Mg_41.6Zn_55.0Nd_3.4 composition. The selected area electronic diffraction (SAED) analysis shows that the icosahedral quasicrystal structure has 5-fold, 4-fold, 3-fold, and 2-fold symmetry zone axes. The thermodynamic stability of the icosahedral quasicrystal is investigated by differential scanning calorimetry (DSC) in the annealed alloys. When annealed above 300°C, the Mg₄₀Zn₅₅Nd₅ quasicrystal is found to decompose into a stable ternary phase Mg₃₅Zn₆₀Nd₅, a binary phase MgZn, and α-Mg, suggesting that the quasicrystal is a metastable phase in the Mg–Zn–Nd system.
